Traumatic Supra- and Infra-tentorial Extradural Hematoma: Case Series and Literature Review.

Traumatic supra- and infra-tentorial extradural hematoma (TSIEDH) is a rare lesion constituting <2% of all extradural hematomas. There are only a few published articles about TSIEDH. This study included three patients with TSIEDH who were treated and operated at Dr. Soetomo General Hospital, Surabaya, Indonesia, from August 2015 to July 2016. Two patients sustained injuries in traffic accidents and one patient was injured by fall. The male to female ratio was 1:2. Glasgow Coma Scale (GCS) score ≤8 was present in one and GCS score of 9-12 was present in two patients. The brain computed tomography scan verified linear fracture of occipital bone in one and linear fracture of occipital bone with lambdoid suture separation in two patients. Early diagnosis and early surgical intervention of TSIEDH are imperative because the deterioration of TSIEDH is sudden and quick. We presented our experience in treating patients with TSIEDH in Dr. Soetomo General Hospital, Surabaya, Indonesia.
