Tc-99m MDP Bone Scintigraphy and Positron Emission Tomography/Computed Tomography (PET/CT) Imaging in Erdheim-Chester Disease

摘要

Erdheim-Chester disease (ECD) is a rare form of systemic non-Langerhans cell histocytosis with an unknown specific etiology and pathogenesis. Symptoms and findings of the disease depend on the site and extent of involvement. We report the case of a 43-year-old man with ECD who presented with fatigue, sweats, and bone pain. The characteristic lesions of ECD, including involvement of the long bones, were detected on Tc-99m MDP bone scintigraphy and PET/CT imaging.
