title: FDG PET/CT images demonstrating Fournier gangrene with bilateral pelvic muscle extension in a patient with recurrent rectosigmoid cancer.
abstract: A 71-year-old male patient with Parkinsonism was referred for an F-FDG PET/CT scan for suspicious recurrence of rectosigmoid adenocarcinoma. The FDG PET/CT scan revealed increased FDG uptakes in the lower pelvic region around the wall of the rectal stump, with extension to the bilateral pelvic sidewalls and the right gluteous minimus muscle. In addition, multiple small air bubbles were noted in the lesions on the attenuation CT images. Fournier gangrene was diagnosed. After treatment with intravenous antibiotics and debridement with sigmoidoscopic irrigation, the patient was discharged and remained uneventful during clinical follow-up for 50 days.
