Bone tumor mimickers: A pictorial essay.

Bottom Line: These bone tumor mimickers can include numerous normal anatomic variants and non-neoplastic processes.It is important for the radiologist and clinician to be aware of these bone tumor mimickers and understand the characteristic features which allow discrimination between them and true neoplasms in order to avoid unnecessary additional workup.Knowing which lesions to leave alone or which ones require workup can prevent misdiagnosis and reduce patient anxiety.

ABSTRACT
Focal lesions in bone are very common and many of these lesions are not bone tumors. These bone tumor mimickers can include numerous normal anatomic variants and non-neoplastic processes. Many of these tumor mimickers can be left alone, while others can be due to a significant disease process. It is important for the radiologist and clinician to be aware of these bone tumor mimickers and understand the characteristic features which allow discrimination between them and true neoplasms in order to avoid unnecessary additional workup. Knowing which lesions to leave alone or which ones require workup can prevent misdiagnosis and reduce patient anxiety.

Calcaneal pseudocyst and intraosseous lipoma. (A) Lateral ankle radiograph of a 39 year old female with foot pain demonstrates a radiolucency (arrows) in the anterior calcaneus due to decrease in bony trabeculae (B) Lateral ankle radiograph of a 45 year old man with an intraosseous lipoma (arrows) shows a similar radiographic appearance to the calcaneal pseudocyst; however, there is focal central calcification (arrowhead) due to fat necrosis

Mentions: In a similar pattern to Ward's triangle, a radiolucency in the anterior aspect of the calcaneus can be outlined by the major trabecular groups [Figure 4].[7] Although this is a normal appearance, a number of pathologic lesions can occur in this location and form a radiolucent region on radiographs. These tumors include simple bone cyst, giant cell tumor, chondroblastoma, and intraosseous lipoma. Intraosseous lipomas often develop central necrosis which can cause a central dystrophic calcification and tends to have well-defined sclerotic margins.[7]
