腹腔淋巴瘤的磁共振诊断及鉴别诊断价值

分析已经病理证实的２８例腹腔淋巴瘤的磁共振表现，并与８例腹腔结核、２４例淋巴转移瘤的ＭＲＩ表现对照，以提高对本病的诊断、鉴别诊断和判断预后的能力。结果：淋巴瘤的ＭＲＩ表现：（１）广泛分布的淋巴结肿大和Ｔ２信号异常升高。（２）肝脾肿大，尤其是脾明显肿大和Ｔ２信号升高。（３）脊柱Ｔ１信号普遍降低或局限降低。（４）胸水、腹水或骨骼破坏。结论：ＭＲＩ表现对腹腔淋巴瘤的诊断和分期有一定意义，并有助于与腹腔淋巴结结核和转移瘤的鉴别

Evaluation of MRI in the Diagnosis of Abdominal Lymphoma

Magnetic resonance image manifestations of 28 cases of abnominal lymphoma were analysed and compared with those of 8 cases of abdominal tuberculosis and 24 cases of lymph node metastsis in order to improve the diagnosis and differential diagnosis and the judgement of prophylaxis.The results showed that MRI manifestations of lymphoma were:(1) Diffusely distributed lymph node enlargement and extraordinary ascent of T 2 signal.(2) enlargement of liver and spleen, especially marked splenomegaly and ascent of T 2 signal.(3) General of localized descent of vertebral column T 1 signal.(4) Pleural effusion,ascites of destruction of bone.Conclusion:MRI manifestations have certain significance in the diagnosis and staging of abdominal lymphoma and are helpful to differentiate it from abdominal lymphnode tuberculosis and metastasis.
