Arachnoid cyst complicated by spontaneous chronic subdural hematoma in the infant

Abstract

Arachnoid cyst is collections of fluid that develop within the arachnoid membrane because of splitting or duplication of this structure. Arachnoid cyst can present at any age with or without symptoms. Chronic Subdural Hematoma most common in elderly patients several weeks after a head injury prior to onset of symptoms. But here we report 1 year-old-boy presented with epileptic seizures for one month. Computed tomography and Magnetic resonance imaging of brain disclosed that left parietal an arachnoid cyst and fronto-temporo-pareital chronic subdural hematoma. After admission, cyst was excised and hematoma was evacuated through fronto-parietal craniotomy approach. The patient had a good recovery postoperatively. Arachnoid cyst with Chronic Subdural Hematoma in the infant is a serious condition with a high mortality rate. However, surgical resection seems to be very favorable.
