It was therefore decided to include piperacillin-tazobactam and to expand the study: a chest-abdomen-pelvis CT scan did not show any relevant pathological findings, but a transoesophageal echocardiogram revealed an enlarged image (29x14 mm) in the anterior segment of the aortic prosthesis, which continued in the initial segment of the ascending aorta, suggesting a periaortic abscess within the preserved aortic valve (Fig. 1).
A PET/TC scan showed a pathological metabolism of the periaortic valve prosthesis, consistent with a perivascular infectious pathology.

A PET-CT scan showed an increase in the pathological metabolism of the periaortic valve prosthesis, consistent with a perivascular infectious pathology (Fig. 2).
