Multiple enlarged FDG avid mediastinal lymph nodes.
No pulmonary changes.
Splenomegaly.
Radiological findings were suggestive of sarcoidosis versus lymphoma.
From the case:
Sarcoidosis (PET-CT)

CT guided biopsy of the anterior mediastinal nodes revealed sarcoidosis.
Case Discussion
Sarcoidosis is characteristically FDG-avid, and PET-CT has been shown to have high sensitivity for thoracic disease. FDG-PET-CT may be useful for
identification of occult sites of disease
identifying a suitable target for diagnostic biopsy
gauging active inflammatory disease in patients with prolonged symptoms
assessing response to treatment
