A Kommerell diverticulum can occur in a number of anomalies of the aortic arch system 4.
It usually refers to the bulbous configuration of the origin of an aberrant left subclavian artery in the setting of a right sided aortic arch. However, it was originally described as a diverticular outpouching at origin of an aberrant right subclavian artery with a left sided aortic arch.
A Kommerell diverticulum may be asymptomatic, or cause symptoms of oesophageal or tracheal obstruction.
A small rounded density may be seen laterally towards the left of the trachea.
An impression can be seen from left side of oesophagus simulating a double aortic arch.
CT / MRI
Typically shows bulbous enlargement of proximal subclavian artery at its origin from aortic arch, posterior to oesophagus.
It is named after Burckhard F. Kommerell, German radiologist (1901 - 1990).
