Other Nerve Sheath Tumors of Brain and Spinal Cord.

The three main types of nerve sheath tumors are schwannomas, neurofibromas and perineuriomas. Multiple neurofibromas throughout the body are the hallmark of Neurofibromatosis type 1 (NF1). Spinal nerve sheath tumors are classified in the group of intradural extramedullary spinal cord tumors, in which they are the most common type (25-30%).

Schwannomas of Brain and Spinal Cord.

Schwannomas are benign tumors originating from the Schwann cells of cranial or spinal nerves. The most common cranial schwannomas originate from the eight cranial nervevestibular schwannomas (VS). VS account for 6-8% of all intracranial tumors, 25-33% of the tumors localized in the posterior cranial fossa, and 80-94% of the tumors in the cerebellopontine angle (CPA).

Bilateral posterior fracture - dislocation of the shoulders after epileptic seizure in patients with cerebral meningiomas. Triple E syndrome - Review of the literature.

Bilateral posterior fracture-dislocation of the shoulders is a very rare entity with an average rate of 0.6/100000 per year. It was first described in 1902 by Mynter.

A rare case of posttraumatic meningitis presenting with acute hydrocephalus.

Posttraumatic meningitis is a severe complication of traumatic brain injury (TBI) that dramatically increases its mortality. Skull-base fractures increase the risk of posttraumatic meningitis. Posttraumatic hydrocephalus was encountered in 0.
