Cinematic rendering demonstrates asymmetry in the mandible with confirmed fibrous dysplasia exclusion, indicating enhanced diagnostic capabilities in imaging.
A 14-year old boy with pronounced facial asymmetry was referred for [ 99m Tc]Tc-3,3-diphosphono-1,2-propanodicarboxylic acid (DPD) single-photon emission computed tomography / computed tomography (SPECT/CT) of the jaw. The initial clinical suspicion of causative fibrous dysplasia in the retromolar region was ruled out through both imaging and bone biopsy. Instead, [ 99m Tc]Tc-DPD-SPECT/CT confirmed the presence of hemimandibular hyperplasia. Cinematic rendering provided photorealistic images, effectively visualizing the asymmetry of the mandible and teeth, and the underlying increased condylar bone turnover.
