subphrenic abscess
Last reviewed 01/2018
Subphrenic abscesses are localised collections of pus, usually underneath the right or left hemi- diaphragm. Other sites include the lesser sac - beneath the liver - and in the hepato-renal pouch.
They are usually the result of a breach in the integrity of the peritoneum.
Subphrenic abscesses are the commonest intra-abdominal abscess.
