The properitoneal fat pad is a distinctive anatomical structure located in the midline of anterior abdominal wall between the transversalis fascia and parietal peritoneum. It has variable size and configuration depending on the gender and nutritional status of individuals, but CT and MR images of the upper abdomen can readily depict its shape and adipose composition. The purpose of this essay is to illustrate the CT and MRI features of normal properitoneal fat pad, and the spectrum of pathological processes that affect it among patients. This information can be relevant to the practicing radiologists and clinicians for the correct diagnosis and management of such conditions because most lesions of this fat pad produce nonspecific symptoms.
腹膜外脂肪垫是一种独特的解剖结构，位于前腹壁中线，位于腹横筋膜和壁层腹膜之间。它的大小和形态因个体的性别和营养状况而异，但上腹部的 CT 和 MRI 图像可以很容易地描绘出它的形状和脂肪组成。本文旨在阐述正常腹膜外脂肪垫的 CT 和 MRI 特征，以及影响其病变的病理过程。这些信息对于放射科医生和临床医生正确诊断和处理这些疾病具有重要意义，因为大多数该脂肪垫的病变产生非特异性症状。
