腹盆腔恶性淋巴瘤的少见CT表现

Atypical CT Findings of Malignant Lymphoma in the Abdomen and Pelvis Cavity

目的探讨腹盆腔恶性淋巴瘤的少见CT表现。资料与方法分析13例经病理证实的腹盆腔恶性淋巴瘤患者的CT表现,男9例,女4例,年龄25～74岁。非霍奇金淋巴瘤12例,霍奇金淋巴瘤1例。全部病例术前或治疗前均做CT平扫及增强检查。结果腹盆腔恶性淋巴瘤的少见CT表现有:(1)腹膜炎样改变(3/13);(2)腹腔或腹膜后肿块合并坏死灶(5/13);(3)大量腹腔积液(2/13);(4)单发或单侧腹腔脏器浸润(3/13)。结论CT表现不典型的腹盆腔恶性淋巴瘤,术前易被误诊,需综合CT表现及临床资料作出诊断。
