Presentation
Chronic pain syndrome and inflammatory bowel disease. Has required multiple injections for pain relief.
Patient Data
Age: 50 years
Gender: Female
Frontal
Incidental finding of multiple foci of calcification projected over the buttocks bilaterally extending more cephalad on the right.
Axial C+ portal venous phase
Multiple calcifications in the subcutaneous fat of the buttocks.
Axial C+ portal venous phase
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.
