The case of a young woman who developed a traumatic distal anterior cerebral artery ("pericallosal") aneurysm from a roller-coaster ride is described. She presented with a subarachnoid hemorrhage (SAH) restricted to the interhemispheric fissure. The initial angiogram was normal but repeat angiography at 8 days revealed the aneurysm. After craniotomy and clipping the patient made a satisfactory recovery. This is the only reported case of a traumatic aneurysm arising under circumstances not usually considered as trauma. It raises questions about the pathophysiology of the formation of such aneurysms and suggests that traumatic pericallosal aneurysms should be considered in SAH of unknown etiology. This case provides further evidence that repeat angiography occasionally helps reveal an aneurysm when the initial study fails to do so.
本文描述了一名年轻女性因乘坐过山车而发生创伤性大脑前动脉远端（“胼周”）动脉瘤的病例。她表现为仅限于大脑半球间裂的蛛网膜下腔出血（SAH）。初次血管造影正常，但8天后重复血管造影发现了动脉瘤。开颅夹闭术后患者恢复良好。这是唯一一例在通常不被视为创伤的情况下发生的创伤性动脉瘤报告病例。它引发了关于此类动脉瘤形成的病理生理学问题，并提示在病因不明的SAH中应考虑创伤性胼周动脉瘤。该病例进一步证明，当初次检查未能发现动脉瘤时，重复血管造影偶尔有助于揭示动脉瘤。
