T2-weighted magnetic resonance imaging scans. (a) Coronal gradient echo T2-weighted magnetic resonance imaging (MRI): two nodular images with an intermediate signal (tophi) under the external collateral ligament and inside the posterior cruciate ligament of the knee. An external meniscus tear may be seen close to urate deposition. (b) Axial T2-weighted MRI: low signal intensity of both tophi, and marked hypointensity of synovium in a Baker cyst. (c) Axial post-contrast (gadolinium) T1-weighted MRI: thickening and nodular enhancement of the synovium in the suprapatelar recess.
