Space
Subphrenic recesses
Peritoneal spaces beneath the diaphragm
High-yield
The falciform ligament limits direct passage between right and left anterior subphrenic spaces, but is not a sealed barrier to all spread.
Overview
These upper abdominal recesses lie between the diaphragm and the adjacent liver, stomach and spleen. Reflections around the liver divide the region into communicating compartments whose shape influences where fluid collects.
Reference facts
- Boundaries
- Roofed by diaphragm, with liver predominating on the right and liver, stomach and spleen contributing on the left. Falciform and hepatic reflections shape their limits.
- Contents
- Normally a thin lubricating fluid film separates the opposing peritoneal surfaces.
- Communications
- The right side communicates with the right subhepatic region and paracolic gutter. The phrenicocolic ligament limits direct upward spread from the left gutter.
Clinical correlation
A subphrenic abscess may follow abdominal infection or surgery. Diaphragmatic irritation can cause referred shoulder pain, hiccups or a reactive pleural effusion.
