Hydatidosis is a cosmopolitan anthropozoonose common to humans and many mammals. The cervical localization is rare even in endemic countries. We report a case of cervical hydatidosis located in the infra-thyroidian region. The diagnosis was suspected on clinical and radiological examinations(Ultrasonography, computed tomography-scan). The surgical removal of the cyst was difficult because of the inflammatory tissue around the mass. The confirmation of the diagnosis was obtained by the histopathological examination. During the followup, a local recurrence of the disease was diagnosed after 9 mo treated successfully by surgery. The report was made on the infra-thyroidian region.
