BACKGROUND
MCA has several anomalies, such as accessory MCA, duplicated MCA and twig-like MCA, up to now all these reported anomalies were hypothesized to due to the failure in fusion of the primitive arterial network. No anomaly of over fused MCA has been reported.
CASE PRESENTATION
A 59- year- old male was hospitalized with a history of paroxysmal slurred speech and left side headache for a week, his blood pressure was 160/80 mmHg and he manifested mild incomplete motor aphasia at the time of admission. The head and neck CTA and DSA all presented a huge and tortuous left MCA, we diagnosed it an anomaly and termed it over-fused MCA. The patient's speech impairment and headache were relieved by controlling his blood pressure.
CONCLUSIONS
Such an anomaly of over-fused MCA is reported for the first time, it's not needed to put special intervention on the anomaly of the patient temporarily, but more observation are needed.
背景
MCA 有几种异常，如副 MCA、重复 MCA 和树枝状 MCA，到目前为止，所有这些报道的异常都被假设为原始动脉网络融合失败所致。尚未报道过 MCA 过度融合的异常。
病例介绍
一名 59 岁男性因阵发性言语不清和左侧头痛一周住院，血压为 160/80mmHg，入院时表现为轻度不完全运动性失语。头部和颈部 CTA 和 DSA 均显示左侧 MCA 巨大且迂曲，我们诊断为异常，并将其命名为 MCA 过度融合。通过控制血压，患者的言语障碍和头痛得到缓解。
结论
首次报道了这种 MCA 过度融合的异常，目前不需要对患者的异常进行特殊干预，但需要更多的观察。
