Background: Arachnoid cysts are benign extra axial lesions, most commonly located in the fronto temporal region and account for 1% of all intracranial masses. They may remain stable or they may grow in size over time. Reports of spontaneous disappearance of arachnoid cysts are rare.

Case Report: Herein, we report the case of a 1-year-old boy with a middle fossa arachnoid cyst revealed by convulsive seizures, managed with anti epileptic drugs, 13 months later, the patient had one seizure episode, the cranial computed tomography Scan showed nearly total disappearance of the arachnoid cyst and the appearance of subdural hematoma. No surgical intervention was performed. Follow-up CT scans 1 month after admission, showed total disappearance of both the arachnoid cyst and the subdural hematoma.
