Schwannoma's of considerable size arising from the trigeminal nerve are very rare. Here, a case of a large right-sided parasellar mass diagnosed as a trigeminal schwannoma is reported. Complete resection of the tumor was successfully achieved. The patient had an excellent postoperative course.

Intraparenchymal schwannomas are very rare tumors. We present a unique case of intracerebral schwannoma. We report a deep parietal peiventricular intraparenchymal schwannoma in a young adult patient with a history of slowly progressive hemiparesis. Magnetic resonance imaging scan revealed a round-shaped mass lesion in the right parietal periventricular area exhibiting low signal intensity in T1-weighted images and high signal intensity in T2-weighted images, and showed extensive perilesional edema. The lesion showed ring enhancement post gadolinium. It is important to recognize and distinguish a schwannoma from other more common brain tumors as the outcome is good and recurrence is rare.
