Arachnoid cysts comprise approximately 1% of all intracranial space-occupying lesions and etiologies of its formation are believed to be both congenital and acquired. However, very few cases of symptomatic acquired arachnoid cyst have been reported so far in the elderly. Here we report a case of acquired symptomatic arachnoid cyst in an elderly patient. We present here a case of 75 years-old male presenting with seizure-like episode. He was diagnosed bilateral subdural hygroma and left-sided arachnoid cyst by CT. However, he was performed CT 12 years ago, which showed no arachnoid cyst then. We performed microsurgical cyst excision and fenestration to the subarachnoid space. Postoperatively his condition has been excellent so far, with no cyst recurrence.
