Figure 2

Magnetic resonance imaging of the left elbow obtained at the first visit to our department. (a) T1-weighted image (T1WI); (b) fat-suppressed T2-weighted image (T2WI-Fs); and (c) gadolinium-enhanced and fat-suppressed T1-weighted image (Gd-T1WI-Fs). A large low-intensity area is observed in T1WI, and high-intensity area is observed in T2WI-Fs. In Gd-T1WI-Fs, a large low-intensity area enhanced peripherally is noted (arrow). It seems as a large cyst surrounded by synovium.
