| 目的 探讨多房囊性肾癌的超声表现特点,以提高对此病的诊断及鉴别诊断水平。方法 回顾性分析14例经手术病理证实的多房囊性肾癌超声声像图表现以及CT和(或)MR动态增强扫描特点。结果 14例多房囊性肾癌中,囊壁增厚或厚薄不均匀12例,囊壁菲薄均匀2例;其中伴壁结节和(或)隔结节10例,分隔厚薄不均匀9例、纤细均匀5例,分隔呈"车辐轮"状5例;3例病灶内可见囊壁和(或)分隔钙化。彩色多普勒血流显像(CDFI)和(或)能量多普勒血流显像(PDI)在瘤体内检测到星点状或短条状血流信号11例,CT和(或)MRI增强扫描有不同程度增强12例。结论 多房囊性肾癌多表现为多房囊性肿物,边界清楚,囊壁可有局部增厚,分隔粗细不均匀,附壁及分隔结节直径均小于6.0 mm。CDFI和PDI能提高多房囊性肾癌的诊断率。 |

| Objective To discuss the ultrasonic features of multilocular cystic renal cell carcinoma (MCRCC) for the purpose of improving the level of diagnostic and differential diagnostic rate. Methods Ultrasonic and CT or MR features of 14 patients of MCRCC confirmed surgically and pathologically were analyzed retrospectively. Results In 14 patients of MCRCC, the cystic wall was thick and uneven in 12 patients and even in 2 patients. There were mural nodule and (or) septum with nodule in 10 patients. The septation was uneven in 9 patients, even in 5 patients and wheel -like in 5 patients. Calcification of cystic wall and (or) septum were found in 3 patients. Blood signals were detected in the tumors with color Doppler flow imaging (CDFI) and (or) power Doppler imaging (PDI) in 11 patients. Various degrees of cystic wall and septum enhancement were detected with CT and (or) MRI after intravenous administration of contrast material in 12 patients. Conclusion On ultrasonic imaging, MCRCC appears as a well defined multilocular cystic mass with irregular thick cystic wall and (or) septum, with expansile nodule less than 6.0 mm. CDFI and PDI can improve the diagnosis of MCRCC. |
