This paper reports a rare extra-pelvic case of endometriosis involving the superior gluteal nerve, presenting with ill-defined buttock and thigh pain, a Trendelenberg gait, and MRI evidence of atrophic changes in adjacent gluteal and tensor fascia lata muscles. MRI identified a mass along the course of the superior gluteal nerve, hyperintense on STIR and T1-weighted sequences, without enhancement after intravenous contrast, while surrounding edema did enhance. Open biopsy with histology confirmed endometriosis, and the patient was started on hormonal therapy to suppress ovarian activity; the main limitation is that this is a single case report, so broader conclusions are limited. Relevance to endometriosis: the article’s entire subject is endometriosis infiltrating a nerve outside the pelvis, specifically the superior gluteal nerve, directly linking it to endometriosis-associated neural involvement.

Abstract

Endometriosis that involves nerves is rare and usually occurs in the pelvis. We describe a case of extra-pelvic endometriosis that involved the superior gluteal nerve. The patient presented with ill-defined buttock and thigh pain and a Trendelenberg gait. MRI demonstrated atrophic changes in the gluteus minimus, gluteus medius and tensor fascia lata muscles indicating involvement of the superior gluteal nerve. MRI showed a mass in the line of the superior gluteal nerve. The mass was hyperintense on STIR and T1-weighted images and did not enhance after intravenous contrast although surrounding edema did enhance. Histological examination of material obtained at open biopsy showed endometriosis. The patient was commenced on hormonal treatment to suppress ovarian activity.
