摘要 目的:总结腹膜假性黏液瘤的影像学表现,提高影像诊断水平。方法:对两例患者的临床资料进行分析并结合文献深入分析本病影像学的最新进展。结果:例1,男,40岁。以“腹水查因”入院。按结核性腹膜炎治疗。治疗过程中行急性阑尾切除术。MRI影像学表现为肝脏包膜下及肠管周围积液,液体信号为T1WI呈中等程度低信号,T2WI信号明显增高。病理:阑尾黏液囊肿破裂并腹腔、网膜、肠管广泛种植转移,假黏液瘤形成。例2,女,21岁。以“盆腔包块”入院。行左侧卵巢囊肿剥除术,病理示左卵巢黏液性囊腺瘤。经B超示腹腔内各脏器间隙可见无数大小不等液性暗区,呈“蜂窝状”,边界欠清晰;距表皮浅,约5~12mm,并伴有腹水暗区。CT全腹平扫+增强:肝缘外、脾周及整个腹、盆腔内充满大量水样低密度影,其内密度不均,CT值12~48Hu;周围有纤维包膜,内有多个不规则的分房及细小分隔,造影剂增强扫描,分隔有轻度强化,分房更加清晰;肠管分布于水样低密度影内,受压向中央聚拢,未见明显肠管漂浮征象;于肝脾内缘及相当于大网膜、肠系膜处低密度影中可见分支状及网状脂肪密度影;肝脏的外缘形成多弧形压迹。病理诊断:腹膜假性黏液瘤。结论:腹膜假性黏液瘤的术前影像学检查十分必要,B超、CT或MRI检查具有一定的诊断和鉴别诊断价值。
