Maxillofacial imaging findings. A T1-weighted axial image of patient 30. The patient exhibited evident subcutaneous adipose tissue proliferation, with infiltration observed in the temporalis muscle, masseter muscle, and parotid gland, resulting in the loss of normal boundaries. B T1-weighted coronal image of patient 12. Extensive fatty tissue with wide-ranging borders infiltrated superiorly into the temporal muscle. C Sagittal image of patient 1. A soft tissue mass was observed on the affected side of the scalp (white arrow), displaying fat signal. D T2-weighted axial image of patient 18. The submandibular gland of the patient was also affected by fatty infiltration (white arrow)
