We present a unique case of a saccular aneurysm originating from the distal end of the right frontopolar artery (FPA).
This previously healthy, 54-year-old man had sustained a mild head trauma. On admission, he was lethargic, but his neurological examination results were otherwise normal. Neuroradiological studies (including brain computed tomography, magnetic resonance imaging, and cerebral angiography) demonstrated a distal-end aneurysm of the right FPA. The aneurysm was clipped and resected via a right frontal craniotomy.
The postoperative course was uneventful. Pathological examination of the resected specimen confirmed rupture of the wall of a true aneurysm. The patient's medical history was also negative for trauma in the past, previous neurological disease, and vascular collagen disorders. Routine angiography performed 30 days postoperatively demonstrated complete occlusion of the right FPA. The patient was free of focal neurological deficits.
This case demonstrates that not all distally located aneurysms are necessarily mycotic or traumatic.
我们报告一例起源于右额极动脉（FPA）远端的囊状动脉瘤的独特病例。
这位54岁既往健康的男性曾遭受轻度头部外伤。入院时，他嗜睡，但神经系统检查结果其他方面正常。神经放射学检查（包括脑部计算机断层扫描、磁共振成像和脑血管造影）显示右FPA远端动脉瘤。通过右额开颅术对动脉瘤进行夹闭和切除。
术后过程顺利。切除标本的病理检查证实真性动脉瘤壁破裂。患者既往病史中也无既往外伤、既往神经系统疾病和血管胶原疾病史。术后30天进行的常规血管造影显示右FPA完全闭塞。患者无局灶性神经功能缺损。
该病例表明并非所有位于远端的动脉瘤都必然是霉菌性或外伤性的。
