The presence of catamenial epilepsy in patients diagnosed with endometriosis is the symptom that would direct towards a suspected cerebral endometriotic localization. However, data research of medical literature supporting this diagnosis shows a small number of studies and the specific research on medline led to the finding of only four case reports. Hence forward, we will report a case of a patient with the surgical diagnosis of ovarian endometriosis, whom had signs of catamenial epilepsy resistant to medical therapy, and with contraindication to hormone therapy because of cerebral ischemic episodes, subjected to laparoscopic bilateral ovarosalpingectomy.
