Gluteal injection site granulomas

Case contributed by A.Prof Frank Gaillard

Presentation

Incidental finding on CT of the abdomen.

Patient Data

Age: Adult
Modality: CT

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 localised fat necrosis, scar formation and dystrophic calcification.
