Pediatric intramedullary schwannoma without neurofibromatosis: case report.

Pediatric intramedullary schwannoma without neurofibromatosis is extremely rare with only five cases reported so far. We present this rare finding in an 10-year-old boy who presented with a sudden onset of weakness in the lower limbs. An intraoperative diagnosis of schwannoma enabled us to carry out a total excision of the tumor, which resulted in near complete recovery at 10 months follow-up.

Giant cerebral cavernoma. Case report with literature review.

Giant cerebral cavernoma is a rare malformation classified as a brain occult vascular lesion. We report a case of initially misdiagnosed giant cavernous angioma revealed by a spontaneous intracerebral hemorrhage. A 40-year-old woman was admitted with right hemiplegia and altered consciousness occurring 3 days prior to presentation.

Radicular interdural lumbar disc herniation.

Intraradicular lumbar disc herniation is a rare complication of disc disease that is generally diagnosed only during surgery. The mechanism for herniated disc penetration into the intradural space is not known with certainty, but adhesion between the radicular dura and the posterior longitudinal ligament was suggested as the most important condition. The authors report the first case of an intraradicular lumbar disc herniation without subdural penetration; the disc hernia was lodged between the two radicular dura layers.
