Clinical data: Clinical data: Right leg pain
Tenderness over anterior aspect of tibia.
CT & MRI FINDINGS: An expansile lesion in the mid tibial saft involving the anterior cortex with bubbly, multicystic appearance and evidence of partial obliteration of the medullary cavity. Lesion appears hypointense on T1 weighted images and shows heterogeneously hyperintense signal on T2/STIR images. Findings including age and anterior tibail diaphysis location possibly suggest adamantinoma of tibial diaphysis versus other differential of osteofibrous dysplasia.
