目的探讨艾滋病(AIDS)相关淋巴瘤(ARL)的CT表现。资料与方法回顾性分析5例AIDS合并非霍奇金淋巴瘤(NHL)患者的CT表现,并复习文献总结ARL的影像学表现。结果5例AIDS合并NHLCT示:淋巴结肿大4例,其中腋窝淋巴结肿大2例,腹股沟淋巴结肿大1例,纵隔淋巴结肿大2例,腹腔淋巴结肿大3例。5例均有淋巴结外病变,肝脾肿大2例,肝内多发低密度结节2例,胰腺内多发低密度结节1例,肾上腺病变1例,十二指肠病变2例,胆管扩张2例,骨骼病变1例,软组织肿块2例。结论ARL以NHL为主,广泛累及淋巴结及淋巴结以外器官,淋巴结外病变发生率高、且常多脏器受累是其影像学特点。
Objective To explore the CT findings of AIDS-related lymphoma (ARL). Materials and Methods The CT findings of 5 AIDS patients with non-Hodgkin’s lymphoma (NHL) were analyzed retrospectively. The literature review summarized the imaging findings of ARL. Results Five cases of AIDS combined with NHLCT showed 4 cases of lymph node enlargement, including 2 cases of axillary lymph node enlargement, 1 case of inguinal lymph node enlargement, 2 cases of mediastinal lymph node enlargement and 3 cases of abdominal lymph node enlargement. 5 cases had extranodal disease, 2 cases of hepatosplenomegaly, 2 cases of multiple low-density intrahepatic nodules, 1 case of multiple low-density nodules in the pancreas, 1 case of adrenal lesions, 2 cases of duodenal lesions and 2 cases of bile duct dilatation 2 cases, 1 case of skeletal lesions, 2 cases of soft tissue mass. Conclusion ARL is mainly NHL and widely affects organs other than lymph nodes and lymph nodes. The incidence of extra-lymph node lesions is high, and often multiple organ involvement is its imaging features.
