Quadruplets hydatid cysts in brain ventricles: a case report.

An 18-year-old male patient with a hepatic hydatic cyst was admitted with cephalgia and gait disturbances. Radiological examination showed a cystic lesion in his liver and four cystic masses, 2-8 mm in diameter, in the right lateral brain ventricle. All cysts were removed without rupture by way of a right transparietal-transventricular approach, using an ellipsoid forceps designed by ourselves. Albendazole was given postoperatively. Postoperative outcome was excellent in this case except for transient left hemiparesis. To our knowledge, this is the first case of four hydatid cysts in the lateral brain ventricle.
