Echinococcosis or hydatidosis is a cosmopolitan antropozoonosis common to humans and several mammalian species. The disease results from the development of the larval or hydatid form of canine tenia (Echinococcus granulosis) in the body. Intra-muscular hydatic cysts are rare, even in endemic areas. We report an exceptional case of intra muscular calf cyst. We report the case of a 50-year-old female patient with right swollen tumefaction, whose investigation led to the diagnosis of hydatid cyst of the triceps sural muscle Magnetic resonance imaging (MRI) was a great contribution, showing a very evocative aspect of a hydatid cyst. The treatment was surgical, thus allowing healing, but with a risk of recurrence. Hydatid cysts are rarely present in the muscles. The diagnosis must nevertheless be maintained according to the clinical and endemic context. Ultrasonography, and incidentally magnetic resonance imaging, is the exploration tools of choice to confirm the diagnosis before surgery and avoid puncture. Exclusive surgical treatment is indicated, ideally for total pericystic resection without rupture.
