Epidural hematomas generally become manifested within hours after trauma because of progressive obtundation and later transtentorial herniation. However, epidural hematomas located outside the temporal fossa may produce vague neurological symptoms of delayed onset. Emergency operation may not adequately expose those blood clots located in unexpected positions. Computed tomographic (CT) brain scans will reveal the full extent and location of these hematomas. Seven cases of chronic epidural hematoma in various extratemporal locations are reported to emphasize their misleading clinical courses, their demonstration by CT scanning, and the underlying pathophysiology.
硬膜外血肿通常在创伤后数小时内出现，原因是进行性意识障碍以及随后的小脑幕切迹疝形成。然而，位于颞窝外的硬膜外血肿可能会产生延迟出现的模糊神经症状。急诊手术可能无法充分暴露位于意外位置的血凝块。计算机断层扫描（CT）脑部扫描将显示这些血肿的全部范围和位置。本文报告了7例位于颞外不同部位的慢性硬膜外血肿病例，以强调其误导性的临床病程、CT扫描的显示情况以及潜在的病理生理学。
