Eleven echo-free and 37 relatively echo-free peripelvic lesions, primarily interpreted as sinus lipomatosis by experienced sonologists, were examined using CT. Eight echo-free lesions proved to be cysts and only three "fibrous fat". Hypodense peripelvic fat accumulations were not totally echo-free in any of the cases, but tended to show up weak echos.
11个无回声和37个相对无回声的肾周病变，经验丰富的超声科医生初步诊断为肾盂旁脂肪增多症，随后进行了CT检查。8个无回声病变被证实为囊肿，只有3个为“纤维脂肪”。所有病例中，低密度的肾周脂肪堆积并非完全无回声，但往往显示为弱回声。
