目的探讨肾脏乏脂肪血管平滑肌脂肪瘤的CT特点,以提高其认识。方法回顾性分析2011年3月~2016年10月我院经病理证实的13例肾脏乏脂肪血管平滑肌脂肪瘤的CT表现。结果本组病例中,9个病灶呈类圆形/圆形,9个病灶呈外生型生长;8个病灶与肾实质交界表现为“V”形角征,2个“杯口”样改变;CT平扫8个病灶呈略高密度;肾实质期8个病灶呈均匀强化;6个病灶明显强化,3个病灶中度强化,4个病灶轻度强化;动态增强9个病灶呈持续强化。结论 CT密度、形态、生长方式、强化程度及强化方式有助于肾脏乏脂肪血管平滑肌脂肪瘤的诊断,CT表现有一定的特征。
Objective To investigate the CT features of renal dysarthria liposarcoma in order to improve its understanding. Methods The CT findings of 13 cases of renal dysarthria of liposarcoma confirmed by pathology in our hospital from March 2011 to October 2016 were analyzed retrospectively. Results In this group of patients, 9 lesions showed a round / round shape, 9 lesions were exogenous growth; 8 lesions and renal parenchyma at the junction of the performance of the “V” -shaped corner signs, 2 8 lesions were slightly higher density in CT scan, 8 lesions were homogeneously enhanced in renal parenchyma, 6 lesions were significantly enhanced, 3 lesions were moderately enhanced and 4 lesions were mildly enhanced, 9 lesions were dynamically enhanced Lesions continued to strengthen. Conclusion CT density, morphology, growth pattern, degree of enhancement and enhancement methods contribute to the diagnosis of renal aneurysm liposarcoma, CT features have certain characteristics.
