| Popis: | A lipogranuloma is a complication of injecting exogenous oily composites, forming a nodule composed of foreign body histiocytes. These may be seen in the setting of use of anabolic steroids. We present a case of a 52-year-old male with rapidly growing intramuscular masses with accompanying lymphadenopathy and constitutional symptoms. A diagnosis of lymphoma was initially made in view of the multifocal nature of his disease. CT and PET/CT scans were used to profile the extent of disease. However, US-guided biopsy samples demonstrated acute-on-chronic fibro-inflammatory connective tissue, but no evidence of malignancy. A follow-up CT scan showed resolution of most of these masses. Subsequently, a history of self-injected anabolic steroids was obtained. Familiarity of imaging characteristics of lipogranuloma may be helpful in avoiding the pitfall of misdiagnosis in this clinical setting. |
