Chondromyxoid Fibroma : MRI
MRI scan from the same case as the previous two images shows a well-demarcated lesion with a high T2-signal in the proximal tibial metaphysis. It reaches the articular surface without breaching it. With contrast, it shows somewhat heteregenous enhancement. Case produced with permission, courtesy of Dr. Frank Gaillard. Radiopaedia. Complete case is here.
