A single giant frontoparietal intraaxial hydatid cyst in a 5-year-old female: a case report and review of literature.

Echinococcus larval stage or a hydatid cyst, a parasitic disease that passes from animals to humans. Echinococcus granulosus and, less commonly, Echinococcus multilocularis species cause the disease. Intracranial echinococcosis is rare, with an incidence of approximately 1%-2%. Primary and secondary intracranial hydatid cysts can be found. A primary one, the most common type, is always solitary. CT and MRI have significantly contributed to the accurate diagnosis of hydatids. Surgical removal of the cyst is the treatment of choice, resulting in most cases in a complete recovery. In this report, we aim to emphasize the presentation of such an isolated primary cerebral hydatid cyst in a 5-year-old girl with neurological symptoms of a space-occupying lesion. Radiology revealed a giant left frontoparietal hydatid cyst. A cerebral hydatid cyst was operated on. The patient showed an uneventful recovery and was discharged. There was no recurrence at follow-up.
