title: An unusual case of primary lymphoma of the skull base extending from cerebellopontine angle to cavernous sinus and orbit. A case report.
abstract: The authors describe a rare case of a primary central nervous system lymphoma of the cerebellopontine angle, extending into the right cavernous sinus and orbit. The patient presented with multiple right sided cranial nerve palsies and rapidly progressive proptosis and ophthalmoplegia of the right eye. Imaging revealed a cerebellopontine angle mass extending into cavernous sinus. Surgical decompression of the tumor was undertaken through a right sided retromastoid craniectomy. Histopathology revealed Non Hodgkin's lymphoma of diffuse large cell type. There was no evidence of systemic lymphoma. Primary lymphoma of cerebellopontine angle with direct extension into cavernous sinus and orbit is rare and to our knowledge this is the only case reported.
