Introduction

The abdomen consists of four regions:

  • Anterior abdominal wall

  • Abdominal cavity (with viscera)

  • Inguinal canal

  • Posterior abdominal wall

Imaging of the anterior abdominal wall seldom shows significant pathology though certain conditions may be seen on ultrasound, such as a Spigelian hernia.

The abdominal cavity, with all its various viscera, is a rich source of pathological images.

The posterior abdominal wall contains the major vessels. The kidneys and ureters have been included as abdominal viscera, though they are really constituents of the posterior abdominal wall.
