This case report and systematic review highlight magnetic resonance imaging as the preferred modality for visualizing extrapelvic sciatic nerve endometriosis, presenting a case of an endometrioma within the right sciatic nerve.

Abstract

Endometriosis (EN) is a common gynecological condition characterized by the presence of functional endometrium located outside the uterine cavity. Sciatic nerve (SN) is rarely affected by EN. Magnetic resonance imaging allows a direct visualization of the spinal and SN, and it is the modality of choice for the study of SN involvement in extrapelvic EN. We report a case of an endometrioma located in the right SN with a systematic review of the literature.
