Bone scan in Erdheime Chester disease [Persian]

Abstract

In spite of very high sensitivity, bone scan is quite nonspecific in evaluation of bony lesions. In interpretation of bone scan special attention to patient's clinical presentation and correlation with other lab and imaging modalities should be paid. In this report a patient with Erdheim Chester disease a rare and unusual form of lipidosis is presented and the pattern of 99mTc-MDP bone scan and other imaging modalities are discussed.
