Aneurysm of Anterior Inferior Cerebellar Artery-posterior Inferior Cerebellar Artery Variant.

Aneurysms arising from anterior inferior cerebellar artery-posterior inferior cerebellar artery (AICA-PICA) variant are extremely rare. They usually present with subarachnoid hemorrhage. This is probably the second case report of a large thrombosed AICA-PICA variant aneurysm presenting as a cerebellopontine angle mass lesion with cranial nerve palsy, managed successfully by surgical clipping.

Long term outcome in surgically treated posterior fossa epidermoids.

Objectives: To study posterior fossa epidermoids treated surgically at our institute and to compare their long term outcome with respect to extent of surgical decompression.

Materials And Methods: Retrospective analysis of 50 cases of posterior fossa epidermoid surgically treated at our institute between 1997 and 2007.

Results: The mean duration from onset of symptoms to surgery was 2.
