Hydatid cyst of the brainstem: The rarest of the rare locations for echinococcosis

Abstract

Hydatidosis, caused by the larval stage of Echinococcus granulosus, is a zoonotic disease typically affecting the liver and lungs. Cerebral localizations are rare, especially in the brainstem. We present a case of a 9-year-old boy with a brainstem hydatid cyst. The patient exhibited progressive walking difficulties and limb impairment. MRI revealed a brainstem mass consistent with a hydatid cyst. Due to the lesion's size and location, surgical intervention was necessary. The cyst was decompressed and removed without complications, followed by albendazole treatment. Postoperative recovery was uneventful, and the patient showed no signs of recurrence after 2 years. This case highlights the importance of early diagnosis, precise surgical techniques, and thorough postoperative care in managing rare cerebral hydatid cysts.
