QuestionChoice
The subphrenic recesses are potential spaces in the supracolic compartment of the greater sac, between the diaphragm and liver. Pelvic malignancies may spread to the right subphrenic and subhepatic spaces via transcolemic spread through the right paracolic gutter.

QuestionChoice
The subphrenic recesses are potential spaces in the supracolic compartment of the greater sac, between the diaphragm and liver. The subphrenic recesses are clinically important because they are a potential site of abscess formation.

QuestionChoice
The infracolic compartment lies below the transverse mesocolon. It is divided into a right and left side by the mesentery of the small intestine. Again, the infracolic compartment is clinically important because it is a potential space where excess fluid (e.g. ascites) can accumulate.

QuestionChoice
The epiploic foramen of Winslow is labelled and provides a site of communication between the lesser and greater sac. The epiploic foramen is clinically important for two reasons. First, it is a potential site for an internal hernia. Secondly, the hepatic artery, portal vein and common bile duct all pass through the hepatoduodenal ligament immediately adjacent to the foramen of Winslow.

QuestionChoice
The paracolic gutters lie between the posterolateral abdominal wall and the lateral aspect of the ascending and descending colons. The paracolic gutters freely communicate with the pelvis and are therefore a potential site of metastatic spread of abdominopelvic malignancies. Additionally, infectious fluids may accumulate in the paracolic gutters, thereby making them a potential site of abscess formation.
