【摘要】 目的分析4例盆腔脂肪增多症(PL)的影像和临床表现特点,以期提高对本病的认识。方法搜集经临床和病理证实的4例盆腔脂肪增多症的影像资料,4例均行 CT、超声和静脉尿路造影(IVU)或膀胱造影检查,1例行 MRI 检查,1例行钡灌肠造影,3例行膀胱镜检查。结果 4例盆腔脂肪增多症患者的腹部 X 线片、CT、IVU 与钡灌肠造影均可见"骨盆透明"征;。肾盂和输尿管上段有不同程度扩张积水,输尿管下段狭窄;膀胱抬高呈"梨"形;直肠和乙状结肠向上及外侧推挤移位;3例病理诊断伴有腺性或腺囊性膀胱炎。结论分析 PL 的影像特点,结合临床表现,可以诊断 PL。更多还原

【Abstract】 Objective To investigate the imaging findings of pelvic lipomatosis in 4 cases with clinical correlation.Methods The imaging data of 4 cases with pelvic lipomatosis proved clinically and pathologically were retrospectively analyzed.CT scan,intravenous urography(IVU)or cystography were performed in all cases.MRI was done in one case,barium enema in one case and urinary cystoscopy in 3 cases.Results Hyperlucent areas in the pelvis("transparent pelvis"sign)were demonstrated on plain X-ray film,CT,IVU and barium enema studies.IVU showed bilateral hydronephrosis,stenosis of lower segment of ureter and dilatation of proximal ureter.The bladder was elevated,simulating an inverted pear. Barium enema study revealed that the rectum and the sigmoid colon were pushed laterally and upwards. Three cases had associated with cystitis cystica by pathology.Conclusion The imaging findings of pelvic lipomatosis,together with clinical information,are helpful to establish the diagnosis.更多还原
