59-year-old woman with PVNS of the right TMJ.

FINDINGS: Mandibular opening with minimal deviation (a). Follow-up MRI scan at 2 years demonstrates no recurrence on T1-weighted sequences (b: axial plane; c: coronal plane; d: sagittal plane) (as indicated by the red arrows). After the right axillary mass resection, the operation area is slightly disordered, and no obvious abnormal enhancement is observed after contrast administration.

TECHNIQUE: Philips Ingenia 1.5 T Magnetic Resonance System. T1-weighted sequences (TR: 220, TE: 2.77).
