Acute-on-chronic subdural haematoma : a rare complication after spinal anaesthesia

الملخص EN

A 70 years old man with undiagnosed chronic sudural hamatoma underwent repair of Rt.

Inguinal hernia under spinal anesthesia.

The patient complained of a postoperative headache and a subsequent computed tomography brain scan showed an acute–on–chronic subdural hematoma, with midline shift and impending coning.

The patient recovered completely after surgical decompression.

There is difficulty in diagnosing chronic subdural hematoma in the elderly patient especially with no history of trauma, along with the differential diagnosis of headache, following spinal anesthesia in this age group.
