Abstract:
Contralateral hematoma formation following acute subdural hematoma (ASDH) evacuation is a well-described complication. The most common type of contralateral hematoma is an epidural hematoma. Rarely, ASDH develops on the contralateral side. We report an elderly woman who presented with a post-traumatic ASDH and underwent ipsilateral hematoma evacuation by craniotomy and subsequently developed a contralateral ASDH. Because of the potential consequences of a delayed ASDH, there should be a low threshold for early post-operative imaging following ASDH evacuation, especially in elderly patients and those with additional associated intracranial injuries.
