Traumatic aneurysms at the superior cerebellar arteries after head injury are extremely rare and may be overlooked. Rupture of these aneurysms can cause fatal intracranial hemorrhages; thus, early identification of the entity helps prevent detrimental outcomes.
A patient suffered from sudden severe headache and decreased consciousness level several weeks after a blunt head injury. He received surgery to remove a progressive enlarging subdural hematoma. The diagnosis of a traumatic aneurysm at the superior cerebellar artery was delayed, made only after a recurrent subdural hemorrhage occurred. He received another surgery to obliterate the aneurysm.
The patient could have been treated earlier if traumatic aneurysm had been suspected in the beginning. In addition to the case, the authors also reviewed the literature to clarify the pathophysiology, clinical presentation, diagnosis, and management of the disease.
头部受伤后小脑上动脉创伤性动脉瘤极为罕见，可能被忽视。这些动脉瘤破裂可导致致命性颅内出血；因此，早期识别该病症有助于预防不良后果。
一名患者在钝性头部受伤数周后突然出现严重头痛和意识水平下降。他接受了手术以清除逐渐增大的硬膜下血肿。小脑上动脉创伤性动脉瘤的诊断被延迟，直到复发性硬膜下出血发生后才得以确诊。他接受了另一次手术以闭塞动脉瘤。
如果一开始就怀疑有创伤性动脉瘤，该患者本可更早得到治疗。除该病例外，作者还查阅了文献以阐明该疾病的病理生理学、临床表现、诊断和治疗。
