摘要 目的:探讨肺外炎性肌纤维母细胞瘤(IMT)的影像表现,提高对该病的认识及影像诊断水平,减少误诊。方法:回顾性分析5例经手术后病理证实的肺外IMT患者的临床资料及影像学表现特点,其中3例行免疫组化检查。1例行MRI平扫及增强检查,4例行CT平扫及增强检查,其中有1例加行MRI平扫检查。结果:5例患者中,病灶分别位于右侧上颌窦、肝脏、胃窦、右肾、右侧眼眶。CT表现:4例均可见明显软组织肿块,其中肝脏、胃窦部病灶单发,右侧眼眶及右肾内病灶多发,右侧眼眶内1例病灶密度较均匀,肝脏、胃窦部2例IMT内出现钙化,右肾1例IMT内出现坏死。CT增强扫描时4例表现为明显强化,其中3例表现为渐进性强化。其中右肾1例病灶内见右肾动脉分支血管走行。肝脏内1例动脉期轻度强化,门静脉期及延迟期病灶呈不均匀向心性强化。MRI上右侧上颌窦、右侧眼眶病灶呈等、长T1WI或长T1WI长T2WI信号,并且T2WI压脂序列均为高信号。结论:肺外IMT并无特征性的影像学表现,确诊仍需要病理学相关检查,但是影像学检查可以显示病灶部位以及病灶累及周围情况。
