A 74-year-old man presented with right watershed infarction (initial gadolinium-injected MRI, Figure). Renal function was normal. MRI 4 hours later showed ipsilateral perivascular spaces (PVS) and subarachnoid fluid-attenuated inversion recovery (FLAIR) hyperintensities, probably related to stroke-associated delayed gadolinium leakage (Figure). MRI after 10 days showed complete resolution of subarachnoid/perivascular abnormalities (Figure).

中风后延迟性钆渗漏相关的血管周围和蛛网膜下腔液体衰减倒置恢复高信号

一名 74 岁男性出现右侧分水岭梗死（初始钆注射 MRI，图）。肾功能正常。4 小时后 MRI 显示同侧血管周围间隙 (PVS) 和蛛网膜下腔液体衰减反转恢复 (FLAIR) 高信号，可能与中风相关的延迟钆渗漏有关（图）。10 天后的 MRI 显示蛛网膜下腔/血管周围异常完全消退（图）。
