Abstract

Necrotizing fasciitis (NF) is characterized with rapid involvement of soft tissues and fascias and could be fatal
if not treated properly. Our patient had history of larynx cancer. He had a tracheostomy and developed NF of
the neck and upper mediastinum which is a very rare complication of tracheostomy.

The patient was referred for a Positron Emission Tomography/Computed Tomography (PET/CT) scan after suspicion
of residual lesion on follow up computed tomography (CT). On fluorodeoxyglucose (FDG) PET/CT images there was
moderate increased uptake at the anterior glottic region, in line with residual disease. PET/CT scan showed
progression of the NF involving the neck and upper mediastinum compared to the CT scan performed 10 days
before. On PET/CT a new pulmonary abscess was also noted in the lower lobe of the left lung.

In our case FDG PET/CT played an effective role in the follow up of oncologic disorders. It was also useful in
the follow up and treatment response of NF, which is a rare but potentially fatal infectious and inflammatory
disorder. Positron Emission Tomography/Computed Tomography (PET/CT) could be preferred in the follow
up of serious infectious conditions accompanying primary malignancy.
