Hydatid Cyst of the Psoas: A Report of 3 Cases

Abstract

Background: Hydatidosis is a frequent and benign disease that prevails in an endemic state and remains a real public health problem in our country, where breeding is still traditional. In countries with hydatid-endemic diseases, all locations are possible. Hydatidosis of the psoas represents an exceptional location, observed in about 0.2 to 0.5% of cases. The symptomatology is dominated by painful swelling in the right iliac fossa or right flank, which is the most common reason for consultation, occasionally developing in a febrile situation and being mistaken for a psoas abscess. The abdominal computed tomography (CT) confirmed the diagnosis and allowed us to better specify the cyst's seat and its reports. The treatment consists of a surgical excision by pericystectomy. The results were satisfactory in all cases, and no recurrence was reported in our series. Prophylaxis is the best way to control this parasitosis in endemic areas. Case Reports: Our work is a retrospective study relating to three cases of hydatid cysts of the psoas muscle collected in the department of visceral surgery at Avicenne Military Hospital and Guelmim Military Hospital over 12 years (1998–2010). This work has allowed us to clarify the epidemiological, clinical, and laboratory aspects and the place of medical treatments, radical and conservative surgical, related to cysts.  It allowed us to clarify the epidemiological, clinical, and laboratory features, as well as the role of medical therapies (radical and conservative surgery) for psoas muscle cysts. The disease is more common in men than women, with an average age of 35.
