In order to determine the normal variations of pelvic fat distribution, 25 men and 25 women normal pelvic computer tomography (CT) scans were reviewed. No distinct fat planes were demonstrated between the prostate and pelvic side walls, bladder and seminal vesicles, and prostate and rectum in 69%, 81%, and 86% of the men patients, respectively. Similarly, there were no distinct fat planes between the uterus and pelvic side walls, and uterus and rectum in 86% and 96% of the women patients, respectively. We conclude that there are no distinct fat planes around pelvic organs in the majority of normal people and this may be a major source of error in the CT staging of pelvic tumors.
为了确定盆腔脂肪分布的正常变异情况，回顾了25名男性和25名女性的正常盆腔计算机断层扫描（CT）图像。在男性患者中，分别有69%、81%和86%的病例在前列腺与盆腔侧壁、膀胱与精囊以及前列腺与直肠之间未显示出明显的脂肪平面。同样，在女性患者中，分别有86%和96%的病例在子宫与盆腔侧壁以及子宫与直肠之间未显示出明显的脂肪平面。我们得出结论，大多数正常人盆腔器官周围不存在明显的脂肪平面，这可能是盆腔肿瘤CT分期错误的主要来源。
