Rapid Spontaneous Resolution of Acute Subdural Hematoma

ABSTRACT

Usually, large amount of acute subdural hematoma needs prompt surgical removal. We report a case of rapid spontaneous resolution in a day. A 78-old female was admitted in comatose state after falling off from a bus. Initial brain CT scan revealed large amount of acute subdural hematoma that was completely resolved on follow-up brain CT taken 26hours after craniocerebral trauma. The spontaneous resolution needs redistribution of hematoma and dilution by CSF. The low density space between inner skull table and hematoma may suggest the possibility of spontaneous resolution.
