Presentation
Chronic pain syndrome and inflammatory bowel disease. Has required multiple injections for pain relief.
Patient Data



Incidental finding of multiple foci of calcification projected over the buttocks bilaterally extending more cephalad on the right.



Multiple calcifications in the subcutaneous fat of the buttocks.



6 years later, these lesions are more calcified and there is more soft tissue swelling.
Case Discussion
Calcification in buttock injection sites is relatively common but this is a particularly exuberant case, reflecting the number of injections into subcutaneous fat rather than muscle causing fat necrosis that is initially seen as soft tissue swelling and then progressively calcifies.
