Neurology CP:巨细胞动脉炎1例

2022-01-13 “脑血管病及重症文献导读”公众号 “脑血管病及重症文献导读”公众号

74岁,女性。

74岁,女性。

因眩晕和姿势不稳6个月,急性恶化。

MRI 显示小脑和脑干急性梗死。神经血管评估显示严重的血管损伤,沿椎基底动脉可见多处狭窄和闭塞(图1)。

图1.DWI显示小脑梗死(A)。TOF MRA可见左椎动脉和基底动脉未显影(B)。对比增强MRA显示颅外椎动脉闭塞、颅内椎动脉和基底动脉规则(C)。DSA显示右侧颈外动脉和椎动脉之间的侧支循环(D.a–E.c)

多普勒超声显示沿面动脉的低回声晕征,而PET-CT显示沿椎动脉和其他较大动脉可见氟-18-氟脱氧葡萄糖摄取增加,因此诊断为巨细胞动脉炎(图2)。

图2.面动脉多普勒超声显示低回声晕(A.a),治疗后消失(A.b)。治疗11天后的STAb显示内膜增厚和弹力层碎裂(B.a,B.b)。PET-CT显示椎动脉、锁骨下动脉、髂动脉和胸主动脉[18F]-FDG摄取。

尽管及时使用大剂量类固醇和托西利单抗治疗,这也使随后的颞动脉活检没有得到诊断信息(图2)。
