结节、肿块型局灶性机化性肺炎的CT表现
王术生 俞咏梅[摘要] 目的 分析结节、肿块型局灶性机化性肺炎(FOP)的MSCT征象。 方法 回顾性分析池州市人民医院2013年1月~2018年2月21例经手术或穿刺病理证实的结节、肿块型FOP的CT表现,所有患者均行64排螺旋CT平扫加三期增强检查,部分病灶辅以多平面重建重建显示。 结果 21例FOP中,结节型12例,肿块型9例;所有病灶位于肺野外带或紧贴胸膜,右肺下叶(8例)及左肺上叶(9例)多发;形态不规则20例,圆形小结节1例;边缘清晰15例,模糊6例;弓形征4例,粗长毛刺12例,胸膜增厚粘连16例,胸膜凹陷3例;不均匀强化19例(伴光滑内壁空洞8例),均匀强化2例;明显强化12例,中度强化7例,轻度强化2例,血管穿行征2例。 结论 结节、肿块型FOP CT表现很复杂,根据病灶的位置、形态、强化方式及多平面重建综合判断,有一定的诊断价值。
