title: The nature of humeral pseudocysts.
abstract: In an effort to define the nature of the humeral pseudocyst, we examined a large number of macerated specimens. The area of rarefaction, located in the lateral aspect of the proximal humerus, may be a prominent radiographic finding in young individuals. In older individuals, with loss of trabecular bone in the proximal portion of the humerus, a less obvious rarefaction is present. Precise radiographic features allow differentiation of this normal finding from significant lesions in this region.
