New-onset contralateral delayed extradural haematoma in an operated case of extradural haematoma: life-threatening if not diagnosed early

Head trauma is still a leading cause of mortality in neurosurgical practice. Among various post-traumatic pathologies, extradural haematoma (EDH) is an acute condition that has good neurological outcomes if intervened promptly. New contralateral delayed EDH (DEDH) in an operated case of ipsilateral EDH is a very rare entity, which if not diagnosed timely may lead to devastating outcomes, sometimes even death. We present a case of newly found contralateral DEDH with significant mass effect and midline shift in the immediate postoperative scan, in an operated case of right frontoparietal EDH, which was not found in the initial preoperative scan. A high index of suspicion is needed in cases of unilateral EDH with contralateral skull fracture along with tense dura after the evacuation of EDH, to diagnose rare but life-threatening contralateral DEDH. Routine immediate postoperative CT scan will prevent devastating complications in these kinds of patients.
