Temporomandibular joint (TMJ) effusions are unusual in asymptomatic patients, and thus should trigger a careful search for underlying pathology. It usually precedes osteoarthritis of the TMJ. Effusions are seen in:
Radiographic features
MRI
On PD/T2 weighted sequences, both synovial proliferation and effusions can be high on signal. If necessary, the two can be distinguished by administering gadolinium.
