Aortic Arch Mycotic Aneurysm Due to Scedosporium Apiospermum Reconstructed With Homografts.

Abstract

A 39-year-old female, active parenteral drug user was diagnosed of spondylodiscitis. A computed tomography (CT) scan showed an extensive aortic arch aneurysm. A positron emission tomography (PET)-CT scan, showing significant aortic wall uptake of the tracer through the whole aortic arch and the D8-D9 intervertebral disc, allowed us to suspect an aortitis despite negative blood cultures. The aneurysm was resected and reconstructed with 2 aortic homografts. Cultures of specimens from the aortic wall were positive to the fungi Scedosporium apiospermum. A new PET-CT scan 4 months after surgery showed absence of tracer uptake both at the homografts site and intervertebral disc.
