Supratentorial Extraventricular Anaplastic Ependymoma Presented With Headache in Pregnancy: Case Report and Review of the Literature

Abstract

Supratentorial extraventricular anaplastic ependymoma (SEAE) is a rare type of ependymoma. On magnetic resonance imaging (MRI), generally it is noted with a solid appearance or a mixed solid and cystic pattern. A 28-year-old female was admitted to our clinic with a complaint of increasing headaches in the third trimester of pregnancy and epileptic seizures in the first week postpartum. A superficial cortical lesion was found in the left precentral gyrus anterior, showing as purely cystic on the MRI. Gross total microsurgical resection was performed. Histological and immunohistochemical examinations confirmed the finding of anaplastic ependymoma. In this article, the course of SEAE is described that starting with pregnancy. And SEAE in this patient was investigated regarding different features from other similar cases. Also, the effect of pregnancy on this tumor's growth, which is known to have an embryonal origin, is discussed.
