Traumatic acute subdural hematoma is one of the most common neurosurgical emergencies accounting for 1020% of all trauma cases. It is usually associated with mortality rate ranging 5090% but increases to 90100% in patients receiving anticoagulants. Majority of these patients are managed surgically by evacuation of hematoma depending upon clinical and radiological findings. Acute subdural hematoma with thickness more than 10mm or midline shift more than 5mm should be evacuated regardless of GCS. Patients with acute subdural hematoma thickness less than 10mm or midline shift less than 5mm should undergo evacuation if GCS drops more than 2 points from admission to injury, pupils asymmetrical, fixed or dilated or ICP more than 20mmhg. Whereas conservative treatment is warranted for patients with acute subdural hematoma thickness less than 3mm. There are case reports regarding spontaneous resolution of acute subdural hematomas even with thickness more than 10mm and midline shift more than 5mm but clear incidences are not available. Here in our article we represent a case of young adult with post traumatic acute subdural hematoma which resolved spontaneously within three days after head injury.
