HYDATID CYSTS IN THE PSOAS MUSCLE

Hydatid cysts in the psoas muscle are unusual. The authors report a ca se of a hydatid cyst which had developed within the psoas muscle and w as detected from a mass in the left iliac fossa which was diagnosed be fore surgery by ultrasound and a CT scan, which remain the preferred p rimary examinations for the investigation of masses of this type. The authors discuss the various possible clinical and paraclinical context s and recommend total pericystectomy of a closed cyst as the best trea tment following extraperitoneal illac surgical opening.
