Unusual cause of back pain and dysphagia: a Kommerell aneurysm

Correspondence to Dr Massimo Mattioli; mattio87@libero.it Description An 85-year-old woman came to our emergency department because of back pain and dysphagia that started a few hours before. A saccular aneurysm of the upper wall of the aortic arch with anterior to posterior diameter of 6.5 cm was detected on CT; the volume-rendered reformation of a CT scan performed about a year earlier to stage the lymphoproliferative disease, confirmed the presence of an aberrant right subclavian artery without other relevant findings (figure 1).
