BACKGROUND
Post-traumatic pseudoaneurysm of the middle meningeal artery is a rare entity. We report an atypical case of a delayed presentation as parenchymal hemorrhage due to a ruptured middle meningeal artery pseudoaneurysm.
CASE DESCRIPTION
A 22-year-old man with an alleged history of cranial trauma following a road traffic accident presented 10 days later with a new right temporal intraparenchymal hemorrhage. The CT revealed a differentially hypodense circumscribed structure in the anterior temporal location eccentrically in the hematoma. The cerebral angiogram depicted a pseudoaneurysm arising from the middle meningeal artery. The patient underwent craniotomy and excision of the aneurysm. On follow up, the patient was asymptomatic and had no focal neurological deficits.
CONCLUSION
Despite its rare occurrence, meningeal artery pseudoaneurysm should be considered as a possible etiology of a post-traumatic delayed presentation as an intracerebral hematoma. Prompt diagnosis and management are warranted in view of the mortality and morbidity.
背景
创伤性硬脑膜中动脉假性动脉瘤是一种罕见的疾病。我们报告了一例不典型病例，表现为迟发性脑实质出血，原因是硬脑膜中动脉假性动脉瘤破裂。
病例描述
一名 22 岁男性，据称在道路交通事故后有颅外伤史，10 天后出现新的右侧颞叶脑内血肿。CT 显示在血肿的偏心位置前颞叶有一个不同程度的低密界限分明的结构。脑血管造影显示假性动脉瘤起源于硬脑膜中动脉。患者接受了开颅手术和动脉瘤切除术。随访时，患者无症状，无局灶性神经功能缺损。
结论
尽管硬脑膜中动脉假性动脉瘤很少见，但应考虑其为创伤后迟发性脑内血肿的可能病因。鉴于其死亡率和发病率，应及时诊断和治疗。
