Scapular metastasis from acinic cell carcinoma of parotid gland: A case report

Figure 1 The magnetic resonance examination results consider the high possibility of bone giant cell tumor. A and B: A solid mass located entirely in the left scapula, which showed a mass-like lesion with long T1 (A) and T2 (B) signals; orange arrow: Partially high signal on diffusion-weighted imaging sequence, unclear boundary with surrounding soft tissue, and uneven enhancement on enhanced scan. The left shoulder joint is in place, and there is a cystic proton density-weighted images high signal in the left humeral head; C and D: Regular imaging examinations were performed one year after treatment, orange arrow: The display signal of the lateral azimuth angle is weakened.
