A patient with a history of previous head injury presented with an isodense subdural hematoma with extension into a preexisting middle fossa arachnoid cyst. The latter, suspected on the basis of findings pointing to chronic expansion of the middle fossa, was confirmed in a repeat CT study carried out after evacuation of the hematoma.
