Spinal Intradural Phosphaturic Mesenchymal Tumor. They arise chiefly from the leptomeninges and nerve roots. Intradural tumors form inside the dura and may or may not involve the spinal cord. Radiology … Intradural-intramedullary tumors are located within the dura and spinal cord parenchyma, while intradural-extramedullary tumors are located within the dura but outside the spinal cord parenchyma. Meningioma and schwannoma are the two most common intradu-ral extramedullary tumors, and both are associated with neurofibro-matosis. Intradural spinal tumors: current classification and MRI features. Intradural extramedullary (IDEM) spinal tumors are common pathologies, and despite their name, they can extend beyond dural confinements. Intramedullary tumors are intradural tumors that grow inside the spinal cord. Intradural tumors are located inside the dura mater lining and are further subdivided into intramedullary and extramedullary tumors. MNM. The schwannoma ( S ) has intradural and extradural components. Differential Diagnosis of Intradural (Extramedullary) and Extradural Spinal Canal Tumors 1 Jerome H. Shapiro , M.D. P = vertebral pedicle. Methods A total of 199 patients with spinal intradural extramedullary tumors who underwent preoperative contrast-enhanced MRI between January 2012 and December 2018 were included in this study. … Intradural-intramedullary and -extramedullary tumors account for 20 and 80% of all spinal tumors, respectively. Free Online Library: Intradural Disk Herniation Mimicking a Spinal Tumor: Radiologic Imaging, Pathogenesis, and Operative Management. The lesion was hyperdense on T2-weighted and hypointense T1-weighted images ( Fig. Useful mnemonics to remember the differential diagnoses for intradural extramedullary spinal neoplasms include the following: No More Spinal Masses; MNM; Mnemonics No More Spinal Masses. Clinical Presentation, Radiological Imaging, and Clinical Monitoring of Treatment The clinical and radiological presentation of spinal extradural metastases has been clearly reported elsewhere. The outcome of surgical treatment of intra- and extramedullary intradural metastases is considered to be poor, with rapid clinical deterioration. Imaging of the spine and spinal cord has traditionally been accomplished with plain radiography, myelography, and CT. 10. Some tumors that are predominantly intradural can occur in the extradural compartment as well. The incidence of intradural spinal tumors is reported to be between 1 and 2 per 100,000 population, and they account for 5% to 10% of central nervous system (CNS) tumors. In order to accomplish this objective, reliable criteria must be established to permit separation of extradural and intradural lesions. Extramedullary-intradural tumors include masses originating from the dura/arachnoid and nerves. J Neurosurg Spine 2010; 12: 641–6. 53-1 ). Tumors of the spinal cord are a rare occurrence, constituting 2–4% of central nervous system (CNS) neoplasms. location as either extradural, intradural extramedullary (IDEM), or intramedullary. After radiological confirmation of the tumor, the only way to determine whether the tumor is benign or malignant is to examine a small tissue sample (Biopsy). Extradural benign tumors refer to the benign tumors arising from the vertebral body and neural arches. Similar to that depicted in Figure 65-1 . The clinical, radio-logical, and histopathological characteristics of the lesions are discussed and previous reports reviewed. Our patient is a 14-year-old Madhesi boy presenting with swelling in the posterior triangle of his neck. 26. Spinal tumors are rare and compromise approximately 5–10% of all tumors of the central nervous system in children and young adults. Neoplasms: Part 2, Intradural Extramedullary Spinal Neoplasms Karl A. Soderlund1 Alice Boyd Smith2,3 Elisabeth J. It is important to distinguish between intradural and extradural hemangiopericytomas of the spinal column. Malignant extradural spinal tumors: MR imaging with Gd-DTPA. We analyzed intraoperative ultrasonographic findings of different spinal tumors and their influence on the surgical strategy. There are four types of spinal hematomas: epidural, subdural, subarachnoid, and intramedullary (spinal cord) hematomas. 20, 21 Furthermore, two-thirds of all intradural extramedullary tumors are schwannomas or meningiomas (approximately 60%). Intradural extramedullary spinal tumors (mnemonic) Dr Owen Kang et al. These findings were compared to histologic tumor type from surgical or necropsy samples. Most spinal cord tumors present by compression rather than invasion 3. The question of optimal treatment remains controversial. In cats, the most common extradural tumor is lymphoma that may also affect the spinal cord itself (intradural localization). Intradural spinal cord tumors, although frequently of benign histopathologic origins, can lead to compressive myelopathy and radiculopathy due to rigid architecture of the spinal canal and neural foramina .When neurological deficits are present, including myelopathy and radiculopathy, surgery is considered to prevent further neurological decline. INTRADURAL-EXTRAMEDULLARY TUMORS. ... including new advances in therapeutic radiology such as targeted proton therapy. Spinal neoplasms are classified into three categories by the involvement sites: intramedullary, intradural extramedullary, and extradural compartment. The outcome of surgical treatment of intra- and extramedullary intradural metastases is considered to be poor, with rapid clinical deterioration. While intradural extramedullary spinal disease varies widely, identification of tumors in this location and their radiologic manifestations greatly facilitates narrowing of the diagnostic considerations. N: neurofibroma; M: meningioma; S: schwannoma; M: metastasis; MnM THE NORWEGIAN RADIUM HOSPITAL, OSLO, NORWAY. 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. In case of extradural or intradural spinal cord tumors, the tumor mass may grow slowly which gives unaffected spinal parenchyma time to compensate. Discrimination between spinal extradural meningioma and both intra and extradural meningioma: Case Report ... or lymphoma. acterize spinal tumors and determine their resectability and prognosis.3 Spinal tumors can be classified as extradural, intradural- extramedullary, and intramedullary. The upper part of the disc fragment, at the level when it enters the dura, is “compact”, as usually seen in extradural disc herniations (Fig. MATERIALS AND METHODS: Fourteen confirmed cases of epidural meningioma were retrospectively reviewed, and imaging characteristics and pathologic findings were analyzed to identify the typical features. Spinal Meningioma is the most frequent type of intradural extramedullary tumor. Juxtapositional tumors of the spinal nerve roots have been noted to not only interact with the roots at various vertebral levels, but also differ among patients. 210th St. and Bainbridge Ave., New York 67, N. Y. In this paper we will review the intradural intramedullary spinal cord tumors. In children, however, intramedullary tumors are … It is suggested that a The most common spinal bone tumor is metastasis, while primary bone tumors are much less frequent. Unlike intracranial tumors most primary spinal tumors are benign . Abstract. Lee CH, Hyun SJ, Kim KJ, Jahng TA, Kim HJ. March 20th, 2018. Benign tumors are not commonly found in the spinal column. 1 Other SIEMTs and lesions include arachnoid cysts, hamartomas, and ependymomas, with an incidence between 5.5-7.5% each. Epidemiology. Spinal tumors are classified as extradural, intradural and extramedullary, or intradural intramedullary based upon their anatomic location. FROM THE DEPARTMENTS OF DIAGNOSTIC RADIOLOGY AND MEDICAL ONCOLOGY AND RADIOTHERAPY. To describe the radiological findings of the different types of intramedullary spinal cord tumors. Extradural (epidural): Epidural tumors are usually from metastatic involvement of vertebral bodies Intradural: We report a case of extradural cervical schwannoma in a 14-year-old boy. Background Spinal cord tumors are classified into three groups based on their anatomical location: epidural, intradural extramedullary and intradural intramedullary types. BACKGROUND AND PURPOSE: Spinal epidural meningioma is an uncommon tumor. A large intradural component compresses the spinal cord ( C ) on the right and displaces the cord to the left of midline. Patients present with signs and symptoms of spinal cord or nerve root compression. Methods. Pediatric intradural extramedullary neoplasms encompass the same tumors that affect adults. Spinal Tumors and Tumor-like ... • Lesions usually designated by their relationship to the cord –Extradural –Intradural extramedullary –Intramedullary • Short segment –Less than 2 vertebral segments • Long segment –More than 2 vertebral segments. There have been 34 cases of extradural spinal hemangiopericytomas reported in the literature (1– 3, 5– 8, 10– 16). The most common tumor is a vertebral hemangioma, a slow-growing skeletal and soft tissue tumor that is often encountered as an incidental finding. 22 Schwannomas are solitary, well-circumscribed, encapsulated tumors, which are located eccentrically on peripheral nerves or spinal nerve roots. IDEMs can have both sporadic and syndromic patterns, and various genetic abnormalities are believed to be responsible for these mainly benign pathologies. Withits multi-planar imaging capability, superior contrast resolution, andinherent high signal-to-noise ratio, MRI is best suited to provideinformation regarding the exact location, extent and morphologicalfeatures of these tumors. 2A and 2B), irregular borders and no contrast enhancement. They encompass the tumors that lie outside the dura mater, i.e., vertebral body neoplasia (osteosarcomas, fibrosarcoma, chondrosarcoma, myeloma) and metastasized extradural tumors (carcinoma, sarcoma, melanoma).
