PET scan: findings in a patient with severe cutaneous and systemic sarcoidosis.

摘要

Sarcoidosis is a multisystem disease of unknown etiology characterized by the formation of noncaseating epithelioid-cell granulomas. We present a black female patient with severe cutaneous and systemic sarcoidosis. In the diagnostic work-up a F-18 FDG PET scan demonstrated the extensiveness of the disease. The scan was combined with a low-dose CT for attenuation correction and improvement of the localization of the identified abnormalities. The presented case showed that F-18 FDG PET scan is useful not only in the diagnostic work-up and the assessment of the extent of sarcoidosis activity but also in the follow-up.
