Delayed Extradural Hematoma After Evacuation Of Contralateral Acute Extradural Hematoma

Introduction Traumatic head injury with extradural hematoma (EDH) is seen in 2% of patients. Development of EDH on the contralateral side is an uncommon complication that has been reported in various case reports.Case Report We report here a case of an 18-year-old male who had a road traffic injury. He was diagnosed as a case of left-sided large frontotemporoparietal acute extradural bleed with a mass effect toward the right side. He was managed with urgent craniotomy and evacuation of hematoma. A noncontrast computed tomography (NCCT) scan performed 8 hours after postoperative period showed a large frontotemporoparietal bleed on the right side with a mass effect toward the left side. He was again taken to the operating room and right-sided craniotomy and evacuation of hematoma were performed. A postoperative NCCT scan revealed a resolved hematoma. The patient made a complete recovery in the postoperative period and is doing well.Conclusion Delayed onset epidural hematoma is diagnosed when the initial computed tomography (CT) scan is negative or is performed early and when late CT scan performed to assess clinical or ICP deterioration shows an EDH. The diagnosis of such a condition requires a high index of suspicion based on the mechanism of injury along with fracture patterns. Additionally, change in pupillary size, raised intracranial pressure, and bulging of the brain intraoperatively are additional clues for contralateral bleeding. Neurologic deterioration may or may not be associated with delayed EDH presentation. An early postoperative NCCT scan within 24 hours is recommended to detect this complication with or without any neurologic deterioration.
