Non-Traumatic Epidural Hematoma in Sickle Cell Disease

Abstract

Non-traumatic epidural hematoma is an extremely rare finding in patients with sickle cell disease. Spontaneous intracranial epidural hemorrhage has been associated with coagulopathy, malignancy, and infection, but few cases secondary to sickle cell disease have been reported in the literature. The mechanism of hemorrhage in these patients is often unclear, although previous cases have suggested associations with vaso-occlusive pain crises, bone infarction, and/or vascular malformations. We report a 9 year old male with sickle cell disease type SS who presented with right shoulder pain, headaches, emesis, and no neurological deficits. CT head revealed large mixed density left frontoparietal epidural hematoma leading to complete left lateral ventricle effacement and 0.5 cm left to right midline shift. He subsequently underwent a left parietal craniotomy for evacuation of epidural hematoma from which he recovered well. The prevalence and proposed pathologic process behind this rare complication will be discussed.
