Hydatid Cyst of the Psoas: A Rare Location

Abstract

Hydatid cyst of the psoas is rare even in countries endemic to hydatidosis. We hereby report a case of hydatid cyst of the psoas in a 69 years old patient with a history of hypertension and had received left nephrectomy due to a renal abscess 2 years prior to his admission.

Primary hydatid cyst of the psoas adherent to the aortoiliac axis: a real therapeutic challenge

“…4 The location at the psoas muscle is rare, constituting 3% of all muscle locations. 5 This rarity is justified by the role of hepatic and pulmonary barriers which oppose the migration of hydatid into systemic circulation. 6 The clinical presentation of hydatid cyst of the psoas is atypical.…”

“…It characterizes the evolutionary stages of the Gharbi classification. 5,10 In deep locations such as the psoas, the CT has a diagnostic value for a precise topography. In our case, CT revealed a mass of the left psoas muscle in direct contact with the aortoiliac axis.…”

“…Medical treatment with albendazole is reserved for inoperable patients or local recurrences in conjunction with surgery. 5 It is used with an adult dosage of 400 mg orally, twice a day and a pediatric dosage of 15 mg/kg/day (maximum of 800 mg) for 16 months. 4…”
