Intraventricular ganglioglioma.

Gangliogliomas are mixed tumors consisting of both glial elements and differentiated neurons. Although any part of the central nervous system can be affected, little is known about intraventricular gangliogliomas. A patient with a ganglioglioma is presented in the previously unreported location of the anterior third ventricle at the foramen of Monro, mimicking a colloid cyst. We review all other reported cases of intraventricular ganglioglioma (n=6) to characterize this entity. Intraventricular gangliogliomas typically affect younger patients with female predominance (male:female, 2:5; median age 25 years). Symptoms occur secondary to obstruction of physiological cerebrospinal fluid circulation. Complete surgical resection with re-establishment of cerebrospinal fluid drainage is the goal of treatment.
