Aim: To perform a comprehensive analysis of discordances between contrast-enhanced CT (ceCT) and 18F-FDG PET/CT in the evaluation of the extra-cerebral treatment monitoring in patients with stage IV melanoma. Materials and methods: We conducted a retrospective monocentric observational study over a 3-year period in patients referred for 18F-FDG PET/CT and ceCT in the framework of therapy monitoring of immune checkpoint (ICIs) as of January 2017. Imaging reports were analyzed by two physicians in consensus. The anatomical site responsible for discordances, as well as induced changes in treatment were noted. Results: Eighty patients were included and 195 pairs of scans analyzed. Overall, discordances occurred in 65 cases (33%). Eighty percent of the discordances (52/65) were due to 18F-FDG PET/CT scans upstaging the patient. Amongst these discordances, 17/52 (33%) led to change in patient’s management, the most frequent being radiotherapy of a progressing site. ceCT represented 13/65 (20%) of discordances and induced changes in patients’ management in 2/13 cases (15%). The most frequent anatomical site involved was subcutaneous for 18F-FDG PET/CT findings and lung or liver for ceCT. Conclusions: Treatment monitoring with 18F-FDG PET/CT is more efficient than ceCT and has a greater impact in patient’s management.

The purpose of this paper was to study the value of 18-FDG PET/CT and reassess the value of CT for the characterization of indeterminate adrenal masses. 66 patients with 67 indeterminate adrenal masses were included in our study. CT/MRI images and 18F-FDG PET/CT data were evaluated blindly for tumor morphology, enhancement features, apparent diffusion coefficient values, maximum standardized uptake values, and adrenal-to-liver maxSUV ratio. The study population comprised pathologically confirmed 16 adenomas, 19 metastases, and 32 adrenocortical carcinomas. Macroscopic fat was observed in 62.5% of the atypical adenomas at CT but not in malignant masses. On 18F-FDG PET/CT, SUVmax and adrenal-to-liver maxSUV ratio were significantly lower in adenomas than in malignant tumors. An SUVmax value of less than 3.7 or an adrenal-to-liver maxSUV ratio of less than 1.29 is highly predictive of benignity.

We report two cases highlighting the role of fluorine-18-fluorodeoxyglucose positron emission tomography/computerised tomography (18F FDG PET/CT) in the diagnostic and preoperative workup of indeterminate adrenal masses. Case 1: a 60-year-old man was diagnosed with a large left-sided adrenal mass with indeterminate radiological characteristics on CT. Biochemical investigations ruled out tumour hypersecretion. 18F FDG PET/CT was performed to exclude metastases and identified a pulmonary nodule in the left upper lobe. Histology of the resected adrenal tumour demonstrated a secondary metastasis from an adenocarcinoma of the lung. Case 2: an 88-year-old male was found to have a heterogeneous and vascular left-sided suprarenal mass and a smaller right-sided adrenal nodule. Both adrenal nodules had indeterminate radiological characteristics. Biochemical investigations were negative. PET/CT demonstrated high avidity in the bilateral adrenal nodules but no extra-adrenal FDG avid disease. Histology demonstrated a metastatic carcinoma of pulmonary origin.
