Hereditary multiple exostoses: shoulder osteochondromas

Case contributed by Dr Behrang Amini

Several osteochondromas of the proximal humeral metaphysis facing away from the joint.

Case Discussion

Frontal view of the left shoulder shows expansion of the proximal left humeral diametaphysis with a ground glass matrix and adjacent cortical thinning. There is a left proximal humeral bony excrescence as well as a protrusion of the cortex medially. In addition, there is a bony protuberance projecting from the medial mid left scapula. These findings are suggestive of hereditary multiple exostoses (HME), which is characterised by the presence of multiple osteochondromas.
