Giant PMMA Foreign Body Granulomas with Imaging.

Filler complications have a wide array of presentations including early and late manifestations. A rare late complication is the foreign body granuloma or granulomatous foreign body reaction. We present a case of giant foreign body granulomas developing 7 years after polymethylmethacrylate (PMMA) filler injection. The patient had an excellent response to a single intralesional injection of triamcinolone acetonide and 5-fluorouracil. The unique opportunity to have pretreatment and posttreatment magnetic resonance imaging (MRI) allows for appreciation of the multidirectional expansion of these granulomas as well as the response in this case. Updated treatment recommendations based on the literature review support the use of oral antibiotics, oral steroids, and intralesional therapies. Surgical excision is reserved as an absolute last resort due to potential complications.
