A case of giant aneurysm of the intrapetrous portion of the internal carotid artery, with intracranial and extra-cranial extension in an eight-year-old girl, is reported. Intracranial extension was demonstrated by the presence of a large sac projecting above the petrous shadow in a frontal carotid angiogram, and upward displacement of the middle cerebral artery in the post-ligation angiogram. Extracranial extension was shown clinically as a pulsating mass in the nasopharynx, and also radiologically as a widened medial coronoid space. Erosive destruction of the petrous bone and its neighbourhood produced palsies of the 6th, 7th, 8th, 9th and 10th cranial nerves. There was appreciable recovery in the cranial nerve palsies when the patient was assessed clinically two weeks after ligation of the internal carotid artery.
本文报道了一例8岁女孩颈内动脉岩骨段巨大动脉瘤，伴有颅内和颅外扩展。颅内扩展在额位颈动脉血管造影中表现为一个大囊突出于岩骨阴影上方，在结扎后血管造影中表现为大脑中动脉向上移位。颅外扩展在临床上表现为鼻咽部搏动性肿块，放射学上表现为冠状突内侧间隙增宽。岩骨及其周围的侵蚀性破坏导致第6、7、8、9和10对颅神经麻痹。在结扎颈内动脉两周后对患者进行临床评估时，颅神经麻痹有明显恢复。
