摘要
目的研讨腹膜后恶性淋巴瘤的螺旋CT表现,及时作出诊断及鉴别诊断。方法经穿刺病理检查证实腹膜后恶性淋巴瘤11例,其中NHL10例、HD1例。使用西门子VolumeZoom多层螺旋CT(MSCT),采用平扫+双期增强扫描进行检查,扫描范围从剑突向下至耻骨联合平面。结果11例均能清楚显示腹膜后肿大的淋巴结病灶;肝、胰等临近器官被推移及转移6例;腹主动脉、下腔静脉等临近血管被推移、包埋6例,具有典型的“腹主动脉淹没征”;腹水、胸腔积液各8例;6例伴有胆囊结石及胆囊炎。结论螺旋CT平扫+双期增强扫描是一种效好的无创检查方法。螺旋CT能确定病变范围和转移,达到准确分期,帮助临床判断预后和检测疗效。
Objective To investigate spiral CT manifestation of retroperitoneal lymphoma and make a diagnossis as well as differential diagnosis. Methods In total 11 cases of retroperitoneal lymphoma proved by pathology after biopsy,including 10 case of NHL and 1 case of HD, were studied. Using a SIEMENS Volume Zoom type multislice spiral CT scanner (MSCT), a plain scan and a dual phase contrast enhanced scan were performed. The examination ranged from the level of xiphoid process down to pubic symphysis. Results Enlargement of retroperitoneal lymph nodes were demonstrated in 11 cases. The liver and pancreas were displaced or involved in 6 cases. Major blood vessels including abdominal aorta and inferior vena cava were diaplaced and embedded in 6 cases, representing a typical“abdominal aorta drown sign ”. Pleural effusion or hydroperitoneum was revealed in 8 cases. Cholelithiansis and cholecystitis were shown in6 cases. Conclusion Plain scan and dual phase contrast enhanced scan using MSCT are un-invasive and precise examinations. Spiral CT determines the range and the involvement of lesion, which is valuable for staging, estimating the prognosis and evaluating the effects of treatment.
