Spinal cord tumours account for about 15% of central nervous system neoplasms. Intramedullary tumours arise within the substance of the spinal cord, whereas extramedullary tumours are extrinsic to the cord. About two thirds of spinal cord tumors in adults are extramedullary in location, among which nerve sheath tumors, meningiomas and Filum terminale ependymomas account for the most. Metastatic...

We report a rare situation in which a lipomyelomeningocele and an intramedullary arteriovenous malformation (AVM) occurred together at the T11-L1 level in a 44-year-old man. MR images showed a hypervascular lesion intradurally and a fatty component extradurally. Spinal angiography revealed this lesion to be an intramedullary AVM with multiple feeding arteries from the right T12 and left T10 int...

Intramedullary spinal epidermoid cysts are benign ectopic embryological growths with reported incidence of less than 1% of intramedullary tumors. In this case we report an unusual cervical intramedullary epidermid with liquid contents. A 40-year-old patient presented with progressive weakness of all four limbs of four months duration, bowel and bladder disturbances of two days duration, pain an...

Intramedullary spinal cord tuberculoma in a young, homosexual man with AIDS was detected with the use of MR and confirmed pathologically. MR findings were similar to those seen in other intramedullary lesions, eg, astrocytoma, ependymoma, hemangioblastoma, metastasis, lymphoma, and opportunistic infections. Delineation of the lesion improved with administration of Gd-DTPA; enhancement of the le...

BACKGROUND AND PURPOSE Studies systematically evaluating the detection of intramedullary spinal cord metastasis with PET are lacking. Our purpose was to evaluate the visibility of intramedullary spinal cord metastasis on PET in a single institutional series and to correlate PET and MR imaging features. MATERIALS AND METHODS Patients were included if pretreatment MR imaging identifying an intr...

A 15-year-old male presented with progressive weakness of both lower limbs with urinary incontinence. Magnetic resonance imaging revealed a spinal intramedullary mass at D7-D8 level. The child was operated with a preliminary diagnosis of an intramedullary tumor. Atypical ependymoma and astrocytoma were considered in the differential diagnosis. Perand post-operative histopathological examination...

Intramedullary osteosclerosis, a rare entity, is usually diagnosed after the exclusion of more sinister etiologies. It typically affects the lower extremity and is more common in females. While the lesion may be discovered incidentally during imaging, presenting symptoms may include pain in the affected bone that is exacerbated with physical activity. Laboratory values are normal, and the lesio...

Background: Intramedullary spinal cord abscess is a treatable cause of paraparesis. It can rapidly lead to complete paralysis below the lesion. Case Presentation: In this article two cases of spinal intramedullary abscess in pediatric age (3 and 4-year-old males) are presented. Incidence, clinical presentation, neurologic investigation and treatment are discussed. Conclusion: Although intramedu...

Spinal intramedullary lipoma is a rare lesion accounting for 1% of all spinal masses and 2% of intramedullary tumours [1]. These lesions are commonly associated with spinal dysraphism [2]. The usual location of spinal lipoma is in the cervico-thoracic region [3]. Spinal intramedullary lipomas without spinal dysraphism are very rare and present in only 1% of patients [1,2]. Though CO2 laser and ...
