title: 18F-FDG PET/CT and MRI of necrobiotic xanthogranuloma.
abstract: Necrobiotic xanthogranuloma is a non-Langerhans histiocytic disorder characterized by chronic and progressively enlarging cutaneous plaques and nodules predominantly at the head and facial regions. These lesions exhibit increased F-FDG uptake because of their inflammatory and granulomatous nature. The author presents the F-FDG PET/CT and MRI features of such an uncommon disease in a patient with associated monoclonal gammopathy.
