title: The more you look, the more you find: challenging results on FDG-PET CT in a patient with neurofibromatosis type I.
abstract: BACKGROUND
  FDG-PET/CT is part of the standard diagnostic management of a patients with a large variety of common and less common malignant tumors, based on the increased glucose metabolism within tumors.
  
  
  METHODS
  A hybrid fluorodeoxyglucose positron emission tomography and computed tomography (FDG-PET/CT) was performed in a neurofibromatosis patient to rule out relapse of malignant peripheral nerve sheet tumor. The scan revealed non-malignant neurofibromas, a testis seminoma and hypermetabolic syphilitic granulomata.
  
  
  CONCLUSIONS
  This case stresses the need to rule out infectious diseases when atypical hypermetabolic lesions are present.
