白血病的胸腹部CT表现及其临床价值

CT findings in chest and abdomen of leukemia and their clinical value

目的 :探讨白血病患者的胸腹部CT征象及其病理基础、临床联系。方法 :本组 116例白血病患者 ,男 71例 ,女 45例 ,急性淋巴细胞性白血病 3 0例 ,急性非淋巴细胞性白血病 61例 ,慢性淋巴细胞性白血病 7例 ,慢性粒细胞性白血病 18例。每例均作CT平扫和增强扫描。结果 :急性淋巴细胞性白血病以深部淋巴结浸润为主 2 5 /3 0例 ( 83 %)、急性非淋巴细胞性髓外浸润肺部最多见 3 5 /61例 ( 5 7%)、慢性淋巴细胞白血病以浅表淋巴结浸润为主 6/7例 ( 86%)、慢性粒细胞性白血病以中重度脾大 18/18例 ( 10 0 %)伴浸润 6/18例 ( 3 3 .3 %)显著。结论 :胸腹部CT征象对白血病的诊断、治疗有参考价值。

Objective:To evaluate CT findings of chest and abdomen in patients suffering from leukemia, and the correlation between pathological basis and clinical manifestations.Methods:116 cases were studied with 71 male and 45 female, including acute lymphoid leukemia (ALL) of 30 cases, acute non lymphoid leukemia (ANLL) of 61, chronic lymphoid leukemia (CLL) of 7, chronic myelocytic leukemia (CML) of 18. Plain and contrast enhanced CT scans were performed in each case.Results:Characteristics of infiltrative changes were presented as deep lymphatic changes in ALL(25/30,83%),pulmonary changes in ANLL(35/61,57%),superficial lymphatic changes in CLL(6/7,86%) and moderate or severe splenomegaly in CML(18/18,100%) concomitant with leukemia infiltration (6/18,33.3%).Conclusion:Involvement of lymph nodes and organs by leukemia can be accurately estimated by CT, which is helpful in diagnosis and treatment of leukemia.
