Abstract

A 62-year-old male was hospitalized because of mild ataxia and right hemiparesis. Computed tomography and magnetic resonance imaging clearly demonstrated a mass in the fourth ventricle, and a suboccipital craniectomy was performed. The tumor was tightly adherent to the choroid plexus of the fourth ventricle and was supplied by the choroidal branch of the posterior inferior cerebellar artery. The histological diagnosis was fibroblastic meningioma. One year later, there was no evidence of tumor recurrence. However, the right hemiparesis, which proved to be secondary to a cerebral infarction, persisted.
