Spontaneous resolution of an acute subdural haematoma.

We report a case of a 47 year old man who presented with head injury due to road traffic accident, with CT scan suggestive of large left sided acute SDH with comminuted fracture of occipital bone. Within a few hours, patient showed significant neurological improvement. Follow-up CT scan revealed rapid spontaneous resolution and redistribution of the acute SDH. The proposed hypothesis explaining this rare phenomenon suggests intracranial and extra cranial redistribution as the cause of spontaneous resolution of acute SDH. The intracranial phenomenon is more common of the two. To our knowledge, this is the first case in the literature where both intracranial and extracranial phenomenon played a role in the same patient leading to rapid spontaneous resolution of acute SDH.
