To our knowledge, no prior published reports have discussed the role of 18F-FDG positron emission tomography/computed tomography (PET/CT) in managing this disease. Our case study involved a 66-year-old woman with a malignant melanoma of the uterine cervix. The patient received PET/CT that identified metastases and lesions which had not been detected from her MRI. Serial PET/CT elucidated that the disease was initially limited to the pelvis, but then metastasized to the abdominal para-aortic lymph nodes, followed by extensive metastases to the brain, lungs, breast, supraclavicular, neck, and other abdominal lymph nodes, as observed at 6-month follow-up. PET/CT was used to complement conventional anatomic imaging modalities, and provided a novel modality for whole body screening. Visualization of the metabolic activity of indeterminate lesions may help in staging, re-staging, treatment planning, and prognostic prediction for patients with this rare disease. </p>","PeriodicalId":30445,"journal":{"name":"Acta Radiologica Short Reports","volume":"1 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2012-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1258/arsr.2012.120026","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"31691284","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
