A 49-year-old woman developed bilateral painful facial swellings and redness of skin 4 months after bilateral facial injection of PAAG fillers. On MRI, ill-defined streaky areas of signal abnormalities, hyperintense on axial STIR (arrows in a) and iso- to hypointense on axial T1 W images (arrows in b), were seen in bilateral superior jowl and medial superficial cheek fat compartments with extension to bilateral medial deep cheek fat and buccal fat pads. These areas display reticulated enhancement on post contrast fat saturated T1 W images (arrows in c) suggesting cellulitis/infection. Haematological investigations showed raised inflammatory markers. Patient responded to treatment with antibiotics
