Macroplastique® is a periurethral bulking agent used for the treatment of female stress urinary incontinence. It is composed of polydimethylsiloxane macroparticles suspended in a polyvinylpyrolidone carrier to allow injection. The patient in this case report had increased 18F-FDG avidity on PET scan at the site of prior Macroplastique® injection. This avidity was likely due to a local inflammatory response and did not represent an occult malignancy. Keen clinical judgement is necessary when this PET-avid area is demonstrated in women with prior bulking therapy as this is an incidental benign finding that does not require further invasive management.
