Subdural hematoma complication middle fossa arachnoid cyst

We report a case of a middle aged patient with middle fossa arachnoid cyst that was complicated by subdural hematoma. This was demonstrated by magnetic resonance imaging that remain the most useful diagnostic tool, and providing excellent tissue specificity. Patient was treated by irrigating the hematoma through burrholes. Magnetic resonance imaging in the postoperative period showed a reduction in size of the arachnoid cyst
