Summary: A case of primary malignant melanoma of the conus medullaris depicted at MR imaging is presented. Tumoral histoimmunologic analysis revealed features of malignant melanoma. Because findings for primary melanoma outside the spinal cord were negative, the diagnosis of primary intramedullary malignant melanoma was established. This rare tumor should be suspected when T1-weighted images

Epidemiology. 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. 7 – 9 In adults, extramedullary tumors predominate, accounting for 60% to 75% of intradural masses with intramedullary tumors accounting for the remainder. In children, however, intramedullary tumors are more

It is a relatively rare cause of myelopathy in patients with cancer; compression of the spinal cord by epidural metastatic tumor occurs far more often. Intradural-intramedullary tumors are located within the spinal cord itself, with the most common being ependymomas, astrocytomas, and hemangioblastomas. Intradural-extramedullary tumors are located within the dura but outside of the spinal cord parenchyma, with the most common being meningiomas and nerve sheath tumors (e.g. schwannomas Karikari IO, Nimjee SM, Hodges TR, Cutrell E, Hughes BD, et al.

Intramedullary spinal cord tumors (IMSCT) or primary spinal cord neoplasms are rare lesions that affect only a minority of the population. However, without treatment they can cause significant neurologic dysfunction, morbidity, and potentially mortality. The most commonly used classification scheme is based on the anatomic location of the lesion in relation to the dura mater and spinal cord INTRAMEDULLARY TUMOR OVERVIEW.

INTRAMEDULLARY TUMOR OVERVIEW. General Comments. These Tumors usually arise from cells within the Spinal Cord. The most common are those originating from the Spinal Cord's supporting cells ("glia") and therefore lie within the substance of the Spinal Cord itself. (Please refer to our section on "Brain Tumors" for a discussion of the Glial series of tumors.)

These are further broken down into intramedullary and extramedullary tumors. Intradural-intramedullary Mar 31, 2015 Introduction. Primary spine tumors are rare neoplasms that can lead to significant patient morbidity and mortality., Intramedullary spinal cord Jul 9, 2015 As a result, the treatment of such a tumor as described by Elsberg and Beer had become known as “extrusion of intramedullary tumors.” In 1918, The differential diagnoses for spinal cord lesions include spinal tumors and inflammatory processes.

OBJECTIVE: We sought to study the application of precise intraoperative localization of small intramedullary spinal cord tumors. METHODS: From November 2015 to August 2017, 5 patients with small intramedullary spinal cord tumors were arranged in this group.

For intramedullary spinal cord ependymomas, surgical resection is the mainstay of treatment since the risk of local and intracranial recurrence is extremely low. 40,49,54,56 However, in intramedullary spinal cord astrocytomas, resection can be difficult as distinct tumor-cord interfaces may not exist; the higher grades (WHO grades 3 and 4) tend to exhibit a high rate of both local and distant leads the way. Primary vertebral bone tumors are less frequent extradural spinal tumors ( - ). Extramedullary, intradural spinal tumors (EISTs) are rare. Th ey comprise about - of all spinal tumors. They are distinguished from intramedullary tumors by their extra-axial location. First recorded resec- Paul C.
