Temporoparietooccipital Brain Hydatid Cyst in a FourYear-Old Child: A Rare Case Report

The larval stages of Echinococcus granulosus cause hydatidosis or hydatid disease, which primarily affects children worldwide. It primarily impacts the lungs and liver, but brain hydatidosis is an infrequent condition in the pediatric population. This condition presents with non-specific signs and symptoms. Intracranial hydatid cysts can be diagnosed through brain magnetic resonance imaging (MRI) and histopathological examination of the specimen. In this report, we describe a case of a 4-year-old boy diagnosed with a temporoparietooccipital brain hydatid cyst. The MRI revealed a thin-walled cystic lesion in the left temporoparietooccipital lobe. It showed a significant mass effect and midline shift, with no abnormal wall or solid enhancement and no surrounding edema. Based on these imaging findings, a diagnosis of a brain hydatid cyst was made. The patient underwent surgery, during which the cyst was removed entirely without rupture. Histopathological examination confirmed the diagnosis of a brain hydatid cyst. The patient had a smooth postoperative recovery, began treatment with albendazole, and was discharged in improved health.
