[Hydatid cyst of the cavernous sinus. A case].

The authors report a case of hydatic cyst of the cavernous sinus occurring in a young woman operated on 3 months before for an intracerebral controlateral localization. An opthalmoplegia associated to a partial facial hypoesthesia were the dominant symptom. The topographic diagnosis was evocated by C.T. scan and Magnetic Resonance Imaging and confirmed by surgery. As far as we know this localization has not been reported. The precise origin and the surgical management of this hydatic cyst are discussed.
