Bar graph showing classification of spinal nerve sheath Imaging pediatric spine tumors - Applied Radiology However, in some cases, differential diagnosis needs to be included, especially in cases of extradural meningiomas and malignant peripheral nerve sheath tumors, because of their rare incidence. It caused severe compression of the spinal cord which showed T2 hyperintensity (Figure 1). A pure extradural hemangioblastoma mimicking a dumbbell ... This comprehensive review focuses on the current classification, clinical symptoms, and MRI fe … Primary leptomeningeal, nerve root, extradural, and intradural (including extramedullary and intramedullary) lesions have been reported [4-11]. Spinal metastasis can occur in three regions including the extradural, intradural extramedullary, and intramedullary regions (4). Differential diagnosis Neoplasm - meningiomas (thoracic) - extradural tumors - neurofibromas or schwannomas (spinal roots) - ependymomas - intrinsic cord tumors - metastases (thoracic spine - because of venous drainage of visceral organs through spinal extradural venous plexuses) • lung cancer • breast cancer Most of the spinal hemangiomas are vertebral or intramedullary while pure epidural cavernous hemangiomas are rare. Primary tumors originate in the spine or spinal cord, and metastatic or secondary tumors result from cancer . In patients with metastatic tumours such as extradural tumours, treatment is primary with a goal to preserve neurological functions, stabilizing the spinal and alleviating the pain. Primary tumors of the spine can be benign or malignant (cancer), and can be further subdivided into intradural and extradural neoplasms. Tumor spinal dapat tumbuh di luar dura (ekstradural) atau di dalam lapisan dura (intradural). A spinal tumor is an abnormal mass of tissue within or surrounding the spinal cord and/or spinal column.These cells grow and multiply uncontrollably, seemingly unchecked by the mechanisms that control normal cells. MRI scans of intraspinal melanomas show hypointense signals on T2 . Familiarity with the range of benign and malignant spinal pathology can help the radiologist formulate a comprehensive differential diagnosis. Importantly, the most common tumour type of the spine is secondary metastasis.. Spinal tumours can be classified into intramedullary, extramedullary, and extradural.These can be classified further into either benign or . Intraspinal tumors are usually readily detected by myelography. The differential diagnosis for masses of the cauda equina region is often considered separately. 3) - Extradural (60% of all spinal tumors): They originate outside the dural sac. Chamberlain MC, Tredway TL. Intramedullary spinal tumors are rare, representing 4-10% of all CNS tumors and less than 10% of all pediatric CNS neoplasms 5. In order to accomplish this objective, reliable criteria must be established to permit separation of extradural and intradural lesions. In addition to . Metastatic Spinal Tumors Spinal Tumors 1,2,3,4 •Primary spinal tumors: masses of abnormal cells originating in the spinal cord, dura, or the vertebral bodies that grow out of control •Metastatic spinal tumors: cancer cells originate in another area of the body and spread to the spinal cord, dura, or vertebral bodies via the bloodstream N=69 (intramedullary spinal cord tumors) . Extradural cases are rare in animals despite their commonness in human literature [19,20]. Extradural spinal cord tumors are usually slow growing and progressive over weeks to months Acute onset of neurologic signs may be caused by tumor-induced hemorrhage or ischemia Intramedullary tumors have a more rapid growth rate and have a higher incidence of hemorrhage, ischemia, and necrosis We report a rare case of a purely extradural thoracic spine meningioma in a 70-year-old man, with an unusual progression. Spinal tumors are uncommon lesions but may cause significant morbidity in terms of limb dysfunction. Surgery is mostly performed on spinal tumours to get tissue for the purpose of diagnosis, to relieve the pressure from the spinal cord or to stabilize the spine. Diagnosis of tumors that . 2. In patients with metastatic tumours such as extradural tumours, treatment is primary with a goal to preserve neurological functions, stabilizing the spinal and alleviating the pain. 16 Extradural tumors are located outside the dura, which is the thin covering surrounding the spinal cord. Extradural Spinal Hemangioblastoma Background: Spinal hemangioblastoma (SH) is a low-grade vascular neoplasm that primarily occurs in the spinal cord. Intraoperatively, the lesion was described as a purple, soft, well-circumscribed vascular tumor directly apposed to the dura. Treatment strategies diverge considerably from neoplastic counterparts, and . The differential diagnosis of spinal masses includes neurogenic tumors (schwannoma, neurofibroma) and meningiomas . only indication for a biopsy from the extradural tumor mass in patients with a known primary . General Assessment in Extradural Spinal Tumors •Clinical •Full skeletal x-ray •99tc-MDP scan •Pulmonary CT •Ultrasound abdomen •ESR, CRP, PSA, IgM, alk. They account for 20% of all intraspinal tumors in adults and 35% of all intraspinal tumors in children 8. Most extradural tumors are cancers that have metastasized to the spine. 1. 3) Main types of SPINAL TUMORS . A video showing the resection of a nerve sheath tumour (intradural/extradural) "dumbbell" tumour from the spinal cord. The differential diagnosis of intradural spinal tumors is primarily based on location, but the clinical presentation, age, and gender of the patient are also important factors in determining the diagnosis. Familiarity with the range of benign and malignant spinal pathology can help the radiologist formulate a comprehensive differential diagnosis. Tumor pada spinal adalah kasus yang langka, hanya sekitar 15% dari seluruh kasus tumor sistem saraf pusat dan 90% kasusnya terjadi pada usia >20 tahun, usia yang produktif bagi seseorang. Despite gross total tumor excision and adjuvant radiotherapy, these lesions have a high recurrence rate with poor long-term survivals. 3,4,7,10 Aytar et al. Spinal cord metastases are uncommon, seen in only 0.9-2.1% of autopsied cancer patients in one series. Contrast medium within the lesion on myelography and CT myelography, or no enhancement by Gd-DTPA on MRI, may indicate a cystic lesion rather than a mass lesion. Unknown spinal lesions are commonly encountered either in the presence of symptoms or incidentally. Lung cancer, breast carcinoma, thyroid carcinoma, renal cell carcinoma are common sites of primary that metastasize to vertebral bodies. This article focuses on the spectrum of extradural spinal tumors, accounting for the majority of primary spinal tumors, by comparing the . J Spine Neurosurg 6:2. doi: 10.4172/2325-9701.1000265 Neurologic complications - MYELOPATHY & RADICULOPATHY - Extramedullary Cord / Root Compression. This comprehensive review focuses on the current classification, clinical symptoms, and MRI features of the more common intradural extramedullary and intramedullary neoplastic lesions. INTRADURAL EXTRAMEDULLARY SPINAL TUMORS Onc54 (4) Right C3 neurofibroma: A, B (AP X-ray) - apparent enlargement of right C2-C3 nerve root foramen (arrowheads); preservation of sharp cortical margins indicates slow growth. Anatomical Fig. A retrospective analysis of 15 consecutive adult patients was performed (equal to or older than 18 years) with spinal extradural or intradural-extramedullary tumors confirmed by postoperative excisional biopsy, up to 2 levels treated by minimally invasive surgery using a full endoscopic visualization and the Caspar's retraction system (for cervical, thoracic, and lumbar tumors) over a 4-year . The differential diagnosis of spinal masses includes neurogenic tumors (schwannoma, neurofibroma) and meningiomas [11]. Keywords: 3-Tesla magnetic resonance imaging, extradural, intradural, spinal neoplasm Spinal osseous neoplasms are frequently encountered and can be challenging when present as solitary lesions. Request PDF | Extradural Spine Tumor Mimics | Unknown spinal lesions are commonly encountered either in the presence of symptoms or incidentally. At the level of T8-T9, there is a ventral extradural low T1 and T2 signal intensity lesion, which measures 2.7 (craniocaudal) × 1.3 cm (anteroposterior). Here, we report a dumbbell-shaped spinal extradural cavernous hemangioma with intrathoracic growth on T2-3 in a 64-year-old man complaining of right side infrascapular area back pain with no neurologic deficit. Spinal tumors constitute 1-10% of all pediatric central nervous system tumors. Tumors arise from nerve roots (neurinomas and neurofibromas), vertebrae (most extradural lesions) and/or epidural tissues. LESSONS HBs should be considered among the differential diagnosis of cervical extradural tumors. Rarely, spinal MPNST can be considered amongst the differential diagnoses of an extradural spinal tumor. A. Osteolysis and expansion of the neural arches of D 1 and D2 seen on frontal roentgenogram of the cervical spine. The differential diagnosis is shown in Table 1. This . Histopathology and immunohistochemistry revealed an HB. However, 50% are completely extradural. Extradural myeloma, TI-T2, in a man aged 63. To the best of the authors' knowledge, this is the first case report describing extradural UPS in dogs. A purely extradural location as reported in this paper is quite exceptional. The differential diagnosis for a spinal epidural mass includes: epidural metastasis epidural abscess herniated nucleus pulposus epidural hematoma epidural arteriovenous malformation epidural angiolipoma epidural lipomatosis phosphatase and white cell count •Total spine MRI •CT -spine •WBB classification •Tomita classification. Most common in the thoracic spine, followed by cervical, and lastly lumbar Extradural cervical spinal cord schwannoma in the pediatric population has never been reported in the literature [12, 13]. 1-3 Ependymomas arise from the ependymal cells lining the central canal of the spinal cord, and would be expected to be centrally located . Spinal MPNST, although rare, should be considered among the differential diagnoses for extradural spinal tumors. They can be subdivided according to their cell of origin and whether they are within the cord (intramedullary) or intradural but extramedullary in location. Adult primary intradural spinal cord tumors: a review. The myelographic findings in combination with . Complete tumor resection was accomplished, followed by a C5-6 posterior fusion. However, although the level of the lesion within the spinal canal is accurately determined by this means, a more precise localization is desirable. They may arise from the vertebral bodies or epidural structures, or they may invade the spinal canal secondarily from nearby structures (Fig. This series of twenty extradural spinal tumors, six in the cervical and fourteen in the thoracic region, were studied from the point of view of determining the relationship between the mechanical factors and . Pseudogout could sometimes mimic spinal tumors or hematomas.14,15 Spinal tumor is generally categorized into three groups; namely extradural tumor, intradural extramedullary tumor, and intradural intramedullary tumor.16 Extradural tumors are located outside the dura, which is the thin covering surrounding the spinal cord. As most spinal metastases (more than 98%) occur in an extradural location, anatomical classification of the extradural location is very important (8). A long dura. The interpretation of these mechanical factors may often make the differential diagnosis between extradural and intradural spinal tumors. 12.1). Patients with grade III tumors are more likely to show evidence of recurrence (67% vs 27% for grade II) and have a lower overall survival rate ( 83 ). 2005;15:265-7. spinal extradural tumors in pediatric, adolescent, and young 16. t heeler BJ, Keylock J, Yoest S, Forouhar M. e wing's sarcoma family tumors mimicking primary central nervous system neo- adult patients, and prompt surgical exploration should be plasms. Ependymoma is the most common intramedullary spinal neoplasm in adults, representing 60% of all spinal cord glial tumors. • differential diagnosis of 'multiple bone lesions' • follow-up of bone metastases • non-bone spinal metastases Spinal metastases • spinal metastases • originate most often from arterial seeding • retrograde venous (mainly intra-abdominal tumors) • direct extension (mainly from lung) Spinal metastases Heindel et al. The epidural fat image may be important for the dif-ferential diagnosis between an intradural and extradural lesion. The relative infrequency of Vol. Following a T2-T4 laminectomy and gross total excision of the epidural mass, the patient regained modest neurological function. The patient underwent a T3-T6 laminectomy with uncomplicated complete removal of the extradural tumor. see p. Spin1 >> pain typically precedes signs of cord compression by weeks ÷ months, but once cord This . EXTRADURAL SPINAL TUMORS, VERTEBRAL TUMORS Onc56 (3) 2) neuropathic pain (root / meningeal irritation). In this case, gross total excision of a posterior T2-T4 epidural MPNST resulted in improvement in the patient's original paraparesis. Spinal subdural abscesses (SSAs) are rare pathologies presenting as encapsulated pus located intradurally and extramedullary. extradural tumors are the most common spinal neoplasia in cats and dogs and include primary bone neoplasms (e.g., osteosarcoma, fibrosarcoma, chondrosarcoma, and hemangiosarcoma), round cell neoplasms (e.g., multiple myeloma, lymphoma, and plasma cell tumors), primary tumors arising from paraspinal soft tissues (e.g., liposarcoma, mast cell … highlights that possibility of schwannomas should be considered as a differential diagnosis for intraspinal extradural tumors even in children without NF. Introduction. Sixty percent are intramedullary, 11% intra- and extramedullary, 21% intradural extramedullary, and 8% extradural. Surgery is mostly performed on spinal tumours to get tissue for the purpose of diagnosis, to relieve the pressure from the spinal cord or to stabilize the spine. This comprehensive review focuses on the current classification, clinical symptoms, and MRI features of the more common intradural extramedullary and intramedullary neoplastic lesions. Notably, immunohistochemistry staining helped confirm the dia … This article focuses on the spectrum of extradural spinal tumors, accounting for the majority of primary spinal tumors, by comparing the . recently reviewed 21 studies that . Extradural spinal meningiomas are rare. tumors that invade the surrounding cranial structures, as observed in this case.2 While SNUC is a rare malignancy, metastasis to the spinal cord is extremely uncommon. Tumor in the vertebral body: The tumor is anterior •Tokuhashi score •GSTSG score Primary tumors that appear on the extradural bony spine are less common and are more often benign, but can cause degenerative or . The spontaneous spinal cord herniation is asso-ciated with focal atrophy of the spinal cord and anterior Fig. 1. Primary spinal melanoma of the CNS accounts for only 1% of these CNS lesions and PSM comprises an even smaller percentage [1]. 14,15 Spinal tumor is generally categorized into three groups; namely extradural tumor, intradural extramedullary tumor, and intradural intramedullary tumor. 15 The most common primary tumors are lung 15 and breast and arise either through hematogenous dissemination or CSF spread through the central canal. Extradural spinal tumors are found inside of the spine but not within the dura sac. Tumors are diagnosed as intradural or extramedullary primarily when they enlarge the sub­ arachnoid space. Extradural (Epidural) tumors Extradural (epidural): Epidural tumors are usually from metastatic involvement of vertebral bodies. 2005 Dec. 56 (3):397-406. Extradural spinal meningiomas are extremely rare, more so in the cervical region. 5. In addition we discuss the pathogenesis of these tumors and the . Extradural tumors are the most common spinal tumors in dogs and cats. Intradural extramedullary tumors like schwannoma or extradural tumors like neurofibroma frequently affect the DRG and appear as dumbbell-shaped in 15% of cases [10, 14]. Schwannomas, which are the most common extradural tumors, show the typical dumbbell-shaped appearance (extra- and intradural portions) in 50% of cases. Extradural masses are the largest group, accounting for approximately 55% of spinal tumors. Differential Diagnoses. The differential diagnosis of intradural spinal tumors is primarily based on location, but the clinical presentation, age, and gender of the patient are also important factors in determining the diagnosis. Depending on their location with respect to the dura mater: (see Fig. In a case of vertebral metastatic melanoma, MRI reveals an increased signal intensity in the vertebral body, with soft-tissue extension into the extradural space (2,7). Although relatively uncommon compared with intracranial or extradural spinal masses, the need for a preoperative or non-operative diagnosis is in many ways greater, as biopsy of intradural lesions has the potential to cause devastating neurological impairment. Spinal tumours can be very debilitating, posing a significant risk to patient morbidity and mortality. In addition to tumors, the differential diagnosis should consider nonneoplastic spine tumor mimics, which may be differentiated based on history, physical, and imaging.
