In the short report published by Siek and Spinek, the femoral metaphyseal lesion in question was described as potentially the first described case of a simple bone cyst (SBC) from a Polish background. However, on review of the single radiograph available, we feel the primary and differential diagnoses offered are misleading from a radiographic perspective, with the imaging features overall favoring fibrous dysplasia—probable cystic subtype. As magnetic resonance imaging (MRI) or a histological diagnosis would not be possible in skeletonized remains, the diagnosis must rest on opinion‐based radiology. In this commentary, we illustrate why fibrous dysplasia is the most likely radiological diagnosis and describe why the differentials offered in the original article should not be entertained.
