CT signs of nineteen cases of hemorrhagic renal cysts that surgically and pathologically proved were analyzed. 8 of the 19 cases revealed as high density hemorrhagic lesion. CT signs in those 8 patients include low density rim sign, cyst immerging sign, and perirenal fascia thickening. The other 11 of 19 cases revealed as low density lesion. CT signs include thickened cyst wall and inhomogeneous density of the cystic content. The hounsfield unit of the lesion is correlated with the duration... CT signs of nineteen cases of hemorrhagic renal cysts that surgically and pathologically proved were analyzed. 8 of the 19 cases revealed as high density hemorrhagic lesion. CT signs in those 8 patients include low density rim sign, cyst immerging sign, and perirenal fascia thickening. The other 11 of 19 cases revealed as low density lesion. CT signs include thickened cyst wall and inhomogeneous density of the cystic content. The hounsfield unit of the lesion is correlated with the duration of disease. It is suggested that CT is valuable in diagnosis of high density hemorrhagic renal cysts, and it gives a clue to the diagnosis of low density hemorrhagic renal cysts. 分析经手术和病理证实的 19例出血性肾囊肿的CT征象。结果发现高密度出血灶 8例 ,可见特征性的低密度环征、囊肿隐没征、肾周筋膜增厚等 ;低密度出血灶 11例 ,见囊壁增厚 ,囊内容物密度不均匀。出血灶的CT值与病程相关。提示CT对高密度出血性肾囊肿有较大的诊断价值 ,对低密度出血性肾囊肿能提示诊断 Objective To try to apply the color doppler energy (CDE) to improve the diagnostic rate for cystic renal carcinoma. Methods 12 cases of cystic renal carcinoma that were confirmed with pathology after operation and 2 cases misdiagnosed as hemorrhagic renal cyst were analyzed retrospectively. Results The typical cystic renal carcinoma showed that there were cystic wall, irregular thickened septum and papillary node on the wall. CDE could obtain the better blood signals than CDFI.

Methods 12 cases of cystic renal carcinoma that were confirmed with pathology after operation and 2 cases misdiagnosed as hemorrhagic renal cyst were analyzed retrospectively. Results The typical cystic renal carcinoma showed that there were cystic wall, irregular thickened septum and papillary node on the wall. CDE could obtain the better blood signals than CDFI. The complex renal cyst might be confused with cystic renal carcinoma and biopsy or operation should be adopted. Conclusion CDE technique could show cystic wall and blood supply better and be benefit for diagnosis and differential diagnosis on cystic renal carcinoma. This paper also had discussed the CDE method application. 目的 本文旨在应用彩色多普勒能量图 (ColorDopplerenergy ,CDE)提高囊性肾癌的术前正确诊断率。方法 回顾经手术病理证实囊性肾癌 12例及超声误诊为囊性肾癌的出血性肾囊肿 2例。结果 典型囊性肾癌可见囊壁及分隔不规则增厚及囊壁乳头状结节 ,CDE较CDFI可以更好地在增厚的囊壁或分隔内可探及血流信号。复杂肾囊肿术前不易与囊性肾癌区别 ,必要时针吸活检或手术治疗。结论 CDE技术能够更好地显示囊壁及分隔内的血供状况 ,有助于临床对囊性肾癌的诊断与鉴别 ,本文对CDE的应用方法学也进行了讨论。
