| Abstract: | Aim: To report a case series in which the radiological features of the subcutaneous use of calcium hydroxylapatite (CaHa) dermal fillers are described for the first time. Materials and methods: Five patients with facial hyperattenuating hypermetabolic subcutaneous lesions were identified on 2- [<sup>18</sup>F]-fluoro-2-deoxy-d-glucose (FDG) positron-emission tomography/computed tomography (PET/CT), who gave a history of facial injections to augment physical appearance. Correlation with additional imaging studies was performed. Results: All cases had subcutaneous high attenuation material on CT (range 280-700 HU), which was FDG avid on PET, with a standardized uptake value (SUV) range of 2.9-13.4. Magnetic resonance imaging (MRI) demonstrated a heterogeneous intermediate signal intensity subcutaneous lesion with enhancement post-gadolinium in one case. Conclusions: CaHa dermal filler is hyperattenuating on CT, hypermetabolic on FDG-PET imaging, of intermediate signal intensity on MRI, and is a potential cause of a false-positive imaging study. © 2009 The Royal College of Radiologists. |
