[Uncommon etiology of extradural hematoma].
Intracranial or spinal epidural hematomas are almost always of post-traumatic origin, and rarely related to rupture of a dural vascular malformation or a hemostasis disorder. We report a case of spontaneous cerebral epidural hematoma observed in a young girl with homozygous sickle cell disease. After analysis of post-operative cerebral MRI, showing skull bone infarction inside and around the bone flap, it was considered that the skull bone infarction could be responsible for a diploic venous thrombosis with subsequent "spontaneous" epidural hematoma.
