However, active sarcoidosis lesions are observed to be hypermetabolic on FDG-PET/CT much like malignancies, which may lead to misinterpretation on imaging. In this case report, we present a rare case of sarcoidosis with multisystem involvement including lung, lymph nodes, bone, pleura, and soft tissue that mimicked lymphoma on FDG-PET/CT and responded to corticosteroid treatment.eninfo:eu-repo/semantics/openAccessComputed TomographyLymphomaPositron-Emission TomographySarcoidosisCase Report10.4103/2156-7514.1618505263121382-s2.0-84940863030Q3WOS:000219260600002N/A
