Intracranial schwannoma

The most common place for intracranial schwannomas is the posterior fossa of the brain. Intracranial schwannomas account for 6-8% of all intracranial tumors.

Most commonly, schwannomas arise from the 8th cranial nerve, and less frequently from the 5th, 9th, 10th, and 7th cranial nerves.

The occurrence of a schwannoma not related to the cranial nerves is extremely rare.

Such tumours account for less than 1% of all surgically treated schwannomas. Only 79 cases have been reported in the literature.

In two cases treated the patients were young women with seizures as presenting symptom. Both underwent surgery with the presumptive diagnosis of benign brain tumour.

Good outcome was achieved with total excision of the tumour.

These tumours should be included in the differential diagnosis of supratentorial benign tumours in young adults. Total excision, whenever possible, is the treatment of choice 1).
