title: Be aware of disseminated sarcoidosis with diffuse subcutaneous nodules on F-18 FDG PET.
abstract: Sarcoidosis is a multisystem granulomatous disorder of unknown etiology that typically affects young adults. Definitive diagnosis requires compatible clinical and radiologic manifestations and histopathologic detection of noncaseating granulomas. In recent years, F-18 fluorodeoxyglucose (FDG) positron emission tomography (PET) has been proposed to play a role in the diagnosis and management of sarcoidosis. Although disseminated sarcoidosis has been reported in nearly all organs including the skin, subcutaneous sarcoidosis is relatively rare with few reports using F-18 FDG PET. We report a case of disseminated sarcoidosis with diffuse subcutaneous nodules demonstrating avid F-18 FDG uptake on PET.
