Osteomuscular Hydatidosis

Abstract

Introduction: Muscular hydatid disease is an extremely rare entity. Intramuscular hydatid cysts are usually secondary, resulting from spontaneous spread of the cysts or after operations for hydatid disease in distant regions. Material and methods: A case of multiple muscular hydatid disease is presented, which behaves like a soft tissue tumor that increases in size, with a review of the pertinent literature. Results: MR images showed a mass in the medial intermuscular septum of the thigh, adjacent and anterior to the femoral vascular bundle. Several satellite lesions are also visualized. The extension study shows another lesion between the right lumbar psoas and the paravertebral muscles in the posterior pararenal space. The diagnosis of hydatid disease is established with CNB. The patient underwent surgery in another center for one of the lesions with poor evolution, finally opting for treatment with Abendazole. Conclusion: In geographical regions where hydatid disease is endemic, the hydatid cyst should be included in the differential diagnosis of a cystic mass in the muscle for its correct treatment.
