Cystic echinococcosis is globally distributed and found in every continent except Antarctica. The
disease often starts without symptoms and this may last for years. The symptoms and signs that
occur depend on the cyst's location and size. Hydatid cyst involves all human parts and most
common affected organs are liver and lungs but the incidence of unusual site is only about 8-
10%. Even in regions where echinococcosis is endemic such as Libya, hydatidosis of cervical
muscular region is extremely rare. In this study, we present exceptionally rare case with an
unusual localization of primary hydatid cyst in the muscle of the neck with atypical presentation,
skeletal muscle echinococcosis should be considered in the differential diagnosis of neck
masses, especially in endemic countries. A detailed history taking and MRI imaging are essential
for accurate surgical planning.
