Abstract
BACKGROUND
The usual symptoms of endometriosis are secondary dysmenorrhea, dyspareunia, and infertility, but when located in the retroperitoneal space, it might have atypical symptoms that delay diagnosis and postpone therapy.
CASE
A young nulligravida presented with secondary dysmenorrhea and concurrent cyclic hip pain. Recent laparoscopy was reportedly normal. Computed tomography (CT)-directed percutaneous needle biopsy of a retroperitoneal mass showed endometriosis. Laparotomy with retroperitoneal dissection removed the endometriosis, and operative arthroscopy released strictured hip tendons improving her hip pain and limp.
CONCLUSION
Retroperitoneal endometriosis presenting as hip pain was diagnosed by CT-guided percutaneous needle biopsy permitting removal by a multidisciplinary surgical approach.
