case_images: Ultrasonography examination showed bilateral frond-like villous projections of the synovium and massive effusion in the suprapatellar pouch (Fig. 1).
case_images: Saggital fat saturation T2A images (thick arrow) and sagittal T1A images (thin arrow) shows the fat-containing frond-like synovial mass and suprapatellar projections outlined by concurrent joint effusion in the infrapatellar fat pad and quadriceps fat pillow. The lesion follows the signal intensity of fat on all sequences.
