Omentalisation of a caudal mediastinal abscess in a dog

A caudal mediastinal abscess was diagnosed in a 2‐year‐old German Short‐haired Pointer with acute onset of lethargy, pyrexia and tachypnoea. The abscess was managed surgically by median sternotomy, abscess content evacuation and omentalisation of the abscess cavity via the diaphragm. Although surgical management of mediastinal abscesses has been reported previously, this is the first report to describe successful management of the condition in a dog by omentalisation.
