Case Report of Cerebellar Endometriosis

Abstract

Endometriosis is a disorder in women which is characterized by extrauterine manifestations. We describe a case of cerebellar endometriosis in a 39-year-old woman who underwent posterior fossa decompression multiple times without establishing a correct diagnosis. Her neurologic status progressively worsened due to chronic hydrocephalus and brainstem compression by cysts. Late in the clinical course, histology from the cyst wall was taken that revealed endometriosis with clear cells and positive immunohistology for progesterone and estrogen receptors. Treatment with gestagens was started but did not improve the patient's status. In patients with chronic recurring intracranial cysts and hydrocephalus, cerebral endometriosis should be considered.
