N2 - ABSTRACT: We report the case of a 58-year-old man with mesenteric nodule at CT performed for abdominal pain. In the suspicion of neoplastic disease, he underwent 18F-FDG PET/CT that did not show abnormal uptake. The nodule was monitored alternating CT and MRI. Two years after the first detection, MRI revealed an increase in size, and 18F-FDG PET/CT was repeated for metabolic evaluation, showing increased metabolic activity. In suspicion of neuroendocrine tumor, for anatomical site, slow growth, and clinical symptoms, 68Ga-DOTATOC PET/CT was performed showing focal uptake, indicating high expression of somatostatin receptors. The final pathology report was consistent with high-grade leiomyosarcoma.
