Pontine hydatid cyst in association with an acoustic neurinoma: MR appearance in an unusual case.
نویسندگان
چکیده
Cerebral localization of the larval form of Echinococcus granulosus is a rare occurrence (1-4% of cases of hydatidosis) [1 ] , and usually produces solitary large unilocular (hydatid) cysts located in the supratentorial compartment [2-4]. We report the plain and contrast-enhanced MR appearance of a histologically proved pontine hydatid cyst that was adjacent to a multicystic acoustic neurinoma in the cerebellopontine angle (CPA).

We herein describe a case of an isolated multilocular hydatid cyst occurring in the basilar cisterns, with nondependent levels of different signal intensities shown on MR images. Three portions were visualized on T1-weighted images: the hyperintense inferior aspect, the isointense central part, and the superior aspect of lower signal intensity. The inferior portion was hypointense on T2-weighte...

Introduction: Hydatid disease caused by larval stage of Echinococcus has been recognized endemically in many countries. Liver and lungs are the most commonly affected organs. Involvement of the head and neck region is rare and bony erosion due to hydatidosis is even rarer. Case Report: We report a case of a 17-year-old girl from a poor socio-economic background who presented with a right side...
