Two cases of traumatic interhemispheric subdural hematoma are reported. The first patient had combined convexity and parasagittal subdural hematomas; the second patient had an interhemispheric subdural hematoma which extended over the tentorium. Although most reported cases have followed a subacute clinical course with characteristic lower-extremity monoparesis, both our patients deteriorated rapidly 24 and 48 hours after the injury without warning neurologic signs and died in spite of prompt surgical treatment. Both cases were diagnosed with computerized axial tomography (CT). This examination is particularly valuable in defining the extent of the hematoma and its possible association with other lesions.
报告了两例创伤性大脑镰旁硬膜下血肿。第一例患者合并有脑凸面和矢状窦旁硬膜下血肿；第二例患者的大脑镰旁硬膜下血肿延伸至小脑幕。尽管大多数报告病例呈亚急性临床病程并伴有特征性的下肢单瘫，但我们的两名患者在受伤后24小时和48小时迅速恶化，没有先兆性神经体征，尽管进行了及时的手术治疗仍死亡。两例均通过计算机断层扫描（CT）确诊。这项检查在确定血肿范围及其与其他病变的可能关联方面特别有价值。
