65岁,女性。

既往高血压病史。

因为突发表达性失语就诊,无其他神经功能缺损。

CT 未见颅内出血,CTA 未见血管闭塞。

CT 灌注显示左侧额叶皮层小片灌注异常,CBF 和 CBV增加,为高灌注表现(下图)。CTA(dynamic subtraction CTA rendering of CT perfusion)显示皮层静脉提前充盈(early contrast filling)。不除外动静脉分流:



随后头 MRI 显示相应区域弥散受限,符合缺血的表现(下图):



MRA 未见明显异常。

患者症状患者,随访也未发生其他新的症状。给予氯吡格雷和辛伐他汀治疗。

6周后随访4D-CT 未见任何异常,无 AV 分流的征象。
