Radiological features of the lesion. a. A conventional anterior-posterior radiograph revealed an osteolytic lesion located in the medial superior metaphysis of the right tibia. The sclerotic rim (black arrow) indicated non-aggressiveness. b-e. Magnetic resonance imaging demonstrated oval eccentric osteolytic lesions in the right tibial medial condyle. It appeared non-specifically isointense on T1WI (b), hyperintense on T2WI, both without (c) and with (d) fat suppression, and enhanced heterogeneously on contrast-enhanced T1WI (e). There was endosteal scalloping and cortical expansion but no cortical disruption, periosteal reaction or soft-tissue mass (white arrow), suggestive of non-aggressiveness. Peritumoural oedema (arrowhead) was noted on T2WI with fat suppression (d)
