Primary Hydatid Cyst of Vastus Lateralis Muscle

Abstract

Musculoskeletal system is rarely involved by hydatid cyst. A 42-year-old man was diagnosed as having a cystic mass within right thigh. Preoperative magnetic resonance imaging suggested an unusual location of hydatid disease, although serology was negative. A gray-white coloured cyst within right vastus lateralis muscle was enucleated during surgery. Histopathology confirmed the diagnosis. This case underlies that hydatid disease should be kept in mind in the differential diagnosis of any soft tissue mass especially in regions where it is endemic.
