Hydatid disease is prevalent throughout much of the world. However, bone and muscle echinococcosis are rare and often misdiagnosed. We report three cases: the first case, 38-year-old man had a primary sacral hydatid cyst, the second one, 37-year-old man, and the third one both had a primary muscle hydatidosis of the adductors of left thigh. The treatment was surgical for all three patients. Healing was obtained for the 2 muscular sites whereas the recurrence was the characteristic of the osseous localization despite several surgical resections.
