Multiple gluteal calcified nodules are noted bilaterally, typical of injection site granulomas.
Case Discussion
Gluteal injection site granulomas are a very common finding on CT and plain abdominal radiographs. They occur as a result of subcutaneous (i.e. intra-lipomatous) rather than intramuscular injection of drugs, which cause localized fat necrosis, scar formation and dystrophic calcification.
