Background:
Echinococcosis in humans occurs as a result of infection by the larval stages of taeniid cestodes of the genus echinococcus. Intracranial hydatid cysts usually develop at an intraparenchymal site. Hydatid cyst within the cerebral ventricle is quite unusual.
Methods:
We reviewed the literature on adult intraventricular hydatid cyst and found case reports mainly in children with an only handful of cases in adults. We reported a rare case of cerebral intraventricular (left lateral ventricle) hydatid cyst in a 21-year-old adult female.
Results:
Although cerebral hydatid cysts are most commonly seen in children and young adults cerebral intraventricular hydatid cyst are comparatively rarer in adults.
Conclusion:
The possibility of infection with Echinococcus granulosus should be included in the differential diagnosis of raised intracranial hypertension in patients from endemic areas.
