FDG PET/CT detects benign neurofibromas presenting as nodal masses: Imaging hallmarks of a diagnostic “red herring”

摘要

Multi-modality positron emission tomography/computed tomography (PET/CT) with 18F-fluoro-deoxy-glucose (FDG) depicts the enhancement pattern and metabolic intensity of lesions. Benign lesions with multiplicity, like neurofibromas often mimic similar appearing malignant neoplasms. We, report, a similar case where FDG PET/CT shows imaging hallmarks for diagnosing benign neurofibromas, in a patient with clinical presentation of lymphoma.Keywords: CT, FDG PET, neurofibromas, nodal mass
