We described the clinical impact of ¹⁸F-FDG PET/MR in refining the evaluation of a 39-year-old female with newly diagnosed metastatic urethral adenocarcinoma.We detailed the diagnostic imaging workup focusing our attention on the CT, MR, and ¹⁸F-FDG PET/MR different findings. In this case, ¹⁸F-FDG PET/MR imaging evaluation resulted not only effective but also altered staging and spared additional invasive procedures in the assessment of a metastatic urethral adenocarcinoma. Combining a highly sensitive PET with the increase tissue resolution of MR (PET/MR) may improve abdominal and pelvic lesion detection outperforming PET/CT for this indication.
