This AP radiograph of the tibia of an 11-year-old boy shows a large soap-bubbly lytic lesion involving a large portion of the proximal tibial metaphysis. The margins are well-defined and sclerotic with pseudoseptation going across the lesion that gives the soap-bubbly appearance sometimes seen with solitary bone cysts and fibrous dysplasia. The cortex is thinned out and slightly dilated medially to the point where it is nonexistent in several areas. The central portion of the lesion has a smoky appearance suggesting a solid lesion as opposed to a bone cyst which would have a dark appearance in the center.
