The distal right tibial metaphysis is expanded by virtue of an eccentric multiloculated lesion that shows multiple fluid-fluid levels of hypo- to iso-intense T1 and iso- to hyper-intense T2/STIR signals. The lesion measures 4.7 X 2.9 X 2.2 cm in orthogonal dimensions, has a thick sclerotic low signal margin and narrow transitional zone. The lesion causes endosteal scalloping with no cortical disruption and abuts the physis. No soft tissue component or abnormal marrow signal beyond the confinements of the lesion.
