Case report:

we report the case of a 48-year-old woman with pain in the maxillary sinuses and temporal areas. The presence of subcutaneous facial calcific plaques was confirmed in computed tomography (CT). Both the physical examination and the lab test results were within normal limits. Upon further questioning, the patient mentioned that she had been administered a facial filler product containing calcium hydroxyapatite (CaHA) (Radiesse®) the year before.

Discussion:

CaHA microspheres are radiopaque, making them visible through conventional x-rays, especially CT scans. The characteristic imaging features, typically bilateral and separate from the bone, along with the history of previous injection of this material, should help the clinician recognize this finding and isolate it from other conditions and diseases. Because of the popularity of this facial rejuvenation technique, clinicians should be familiar with the imaging characteristics associated with the deposition of this substance.
