ABSTRACT
ABSTRACT Cholesterol granuloma (CG) is a foreign body-type granuloma that forms in response to cholesterol crystals. Its etiology and pathogenesis are unclear. 18F-FDG is not a tumor-specific agent. Fibroblasts, macrophages, and multinucleated giant cells also take up 18F-FDG. Like sarcoid granulomas or fibrous dysplasia, CG avidly takes up 18F-FDG and can mimic tumor involvement. We present 2 cases of histologically proven CG, which has been misinterpreted as active residual Hodgkin lymphoma lesion.
