Psoas Muscle, An Exceptional Location for Cystic Echinococcosis: About A Case

Abstract

Introduction: Primary extra-hepatic and extra-pulmonary locations of cystic echinococcosis are rare. Psoas muscle, is one of the unusual locations of cystic echinococcosis, few series of cases have been reported. Purpose: report a new case of psoas muscle cystic echinococcosis, and review the literature to discuss diagnostic circumstances and therapeutic modalities Observation: A 29-year-old man, consulted for painful swelling, extending from the right flank of the abdomen to the root of the right thigh. Preoperative diagnosis is facilitated by ultrasound, CT, and serology. The patient is operated by a median laparotomy. The intimate relationship of the cyst with the adjascente structures including the nerve structures prevented the realization of a complete kystectomy. Post-operative evolution is simple. An Albendazole-based medical treatment was associated in post-operative for one year. Conclusion: Psoas muscle is one of the rare locations of cystic echinococcosis. Know how to think about it before any lumbar or iliac cystic formation. Surgical treatment remains the first line of therapy.
