摘要 目的分析宫颈小细胞神经内分泌癌(SCCC)的MRI表现,以提高对该病的诊断水平。方法回顾性分析3例SCCC患者的临床及影像学资料,重点分析其MRI表现。结果 SCCC平扫T1WI均为低信号,T2WI信号混杂,以中等稍高信号为主,DWI上扩散受限,呈明显高信号,ADC图呈明显低信号,3例平均表观弥散系数(ADC)值为0.699×10-3mm2/s。增强后扫描,2例动脉期不均匀明显强化,1例不均匀轻度强化,延迟期3例持续性强化。3例发生盆腔淋巴结转移,2例发生远处骨转移;转移淋巴结融合呈块状,边界模糊,较大者T2信号不均匀,增强后呈花环状或结节状明显强化。结论 SCCC有特征性表现,T2信号不均匀,ADC值比较低,淋巴结转移常见,且较易融合成大块状,这些有助于临床精确诊断SCCC。
