Anterior third ventricle meningioma in an adolescent: a case report

Abstract

A case of an anterior third ventricular meningioma in a 17-year-old girl is presented. Gross total resection of this tumor with minimal morbidity was accomplished by transcallosal exposure through a frontal craniotomy. A review of the literature implies that surgical morbidity and mortality for the removal of third ventricular meningiomas markedly improved with the use of the operating microscope. Despite advanced imaging capabilities, radiographic analysis of a solid third ventricular mass may not always determine tissue diagnosis. In addition, preoperative placement of a ventriculoperitoneal shunt will treat hydrocephalus, but may limit the surgical options for tumor exposure. The differential diagnosis for this solid anterior third ventricular mass is presented, and the method of treatment for this case is discussed.
