A 15-year-old man presented with stupor following a motorcycle traffic accident. The patient was diagnosed with a traumatic left carotid cavernous fistula (CCF) with pseudoaneurysm of the left internal carotid artery. Brain magnetic resonance imaging (MRI) showed transiently restricted diffusion in the left centrum semiovale white matter and lower temporo-occipital area extending to the splenium of the corpus callosum, with high signal intensity on diffusion-weighted imaging. On the 35th day of admission, the patient had complete neurological recovery and a follow-up brain MRI revealed complete resolution of the lesions in the left centrum semiovale and splenium of the corpus callosum. These clinical and radiological features are highly suggestive of complete reversal of diffusion restriction after successful embolization of traumatic CCF.
一名15岁男性在摩托车交通事故后出现昏迷。患者被诊断为创伤性左颈内动脉海绵窦瘘（CCF）伴左颈内动脉假性动脉瘤。脑部磁共振成像（MRI）显示左侧半卵圆中心白质和颞枕下部区域至胼胝体压部出现短暂性扩散受限，在扩散加权成像上呈高信号强度。入院第35天，患者神经功能完全恢复，脑部MRI随访显示左侧半卵圆中心和胼胝体压部病变完全消失。这些临床和影像学特征高度提示创伤性CCF成功栓塞后扩散受限完全逆转。
