Subdural haematoma in an adult due to hypernatraemia.

Neurological manifestations are quite common in hypernatraemia but subdural haematoma due to hypernatraemia is very rare in adult population. We report a case of 50 year old female patient who presented with acute acalculus cholecystitis who subsequently developed persistent hypernatraemia with multiple subdural haematomas and patient died. Patient died because of persistently raised intracranial tension, before she could be taken up for surgical evacuation of subdural haematoma.
