title: Chronic epidural hematomas.
abstract: 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.
