: Hydatid disease is a public health problem in endemic areas. Although the liver and lung are its most commonly locations, it rarely affects other tissues. A 41-year-old female patient was admitted to our clinic with a palpable, fixed mass over the left calf. On MRI, a subcutaneous oval cystic lesion over the left gastrocnemius muscle, containing round-shaped daughter cysts hypointense and hyperintense on T1- and T2-weighted scans, respectively, was detected. Her serological test for hydatic disease was positive. Her whole body was scanned for any other organ involvement, but scans were all negative. During surgery, a well capsulated cyst was excised en bloc. On histological examination, a hydatid cyst was confirmed. She was treated with albendazol. There were no local or systemic recurrences at 1 month of follow up. Primary subcutaneous tissue involvement is a rarely reported entity in the literature. To the best of our knowledge, this is one of only three cases reported of a primary subcutaneous hydatid cyst detected in the leg.
