Causative organism for hydatid disease in humans is Echinococcus granulosus and few other types of tapeworm. In a life cycle of Echinococcus, humans are accidental hosts who get infected by ingestion of the eggs of the parasite containing oncosphere, from close contact with infected animals or from the ingestion of contaminated food or water. Most common site of involvement in humans is liver, followed by the lungs. Musculoskeletal involvement in hydatid disease is mostly secondary to liver or lung hydatid. Primary musculoskeletal involvement is a rare manifestation of hydatid disease. We report herein a case of primary hydatid disease involving pubic bone, which is a rare site and only few cases of pubic bone hydatid cysts are reported in literature. Imaging, especially Magnetic Resonance Imaging, plays a pivotal role in reaching the diagnosis as in our case and helps in differentiating from other pathologies.
