Two patients are described who had areas of rarefaction in the humeral heads that were biopsied and found to be normal bone. Almost all humeral heads have an area of localized rarefaction laterally, and when very pronounced this can be confused with a lytic lesion. These pseudocysts are so radiographically characteristic that they should not be biopsied.
描述了两名患者，其肱骨头出现骨质稀疏区域，经活检发现为正常骨骼。几乎所有肱骨头外侧都有局部骨质稀疏区域，当这种情况非常明显时，可能会与溶骨性病变相混淆。这些假囊肿在影像学上具有特征性，不应进行活检。
