Fig. 4B —Incidental enchondroma of distal femur and small subchondral cyst or intraosseous ganglion in 53-year-old woman with knee pain associated with medial and lateral meniscal tears. Coronal T1-weighted (A, TR/TE, 550/15) and fat-suppressed T2-weighted (B, 4,867/50) MR images reveal proximal tibial epiphyseal lesion with marrow replacement and high signal intensity on long-TR image (arrows). These intrinsic MR characteristics simulate enchondroma.
