title: [Rapid spontaneous resolution of acute subdural hematoma].
abstract: Acute subdural hematomas are usually neurosurgical emergencies, although a conservative therapy is indicated in selected cases. In some of these patients a progressive resolution is appreciated. However, rapid spontaneous resolution of an acute suddural hematoma is seldom reported. A patient with antecedent of chronic alcoholism and spontaneous resolution of acute subdural hematoma in less than 18 hours after the head injury is described. The possible mechanisms of this rapid resolution are discussed. A tear in the arachnoid with spilling of CSF into the subdural space and the effect of intracranial antihypertensive measures together with cerebral atrophy, are factors that possibly contribute to dilution and redistribution of blood with hematoma disappearing in CT scan.
