Exceptional location of hydatid cyst: primary hydatid disease of the mesentery

The hydatid cyst of the mesentery is a rare localization of hydatid disease; most often it is secondary to a hydatid cyst of the liver. Its primitive form remains exceptional and is due to an arterial haematogenous dissemination. We report a case of primary hydatid cyst of the mesentery in a patient of 43 years. The diagnosis was established by ultrasonography and computed tomography with positive hydatid serology. The aim of this work is to remind, through this observation and a literature review, clinical aspects and therapeutic management of this disease.
