Bone tumor mimickers: A pictorial essay.

Mhuircheartaigh JN, Lin YC, Wu JS - Indian J Radiol Imaging (2014)

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.

Figure 5: Dorsal defect of the patella. A 38 year old female with left knee pain. (A) AP radiograph of the knee demonstrates a focal radiolucency (arrow) in the superolateral aspect of patella (B) Sagittal PDW MRI image shows a focal area of cortical irregularity with intact overlying hyaline cartilage (arrow)

Mentions: A subarticular abnormality in the superolateral aspect of the patella is known as the dorsal defect of the patella. It is seen in approximately 1% of the population and can be bilateral.[9] The dorsal patellar defect can appear as a 1-2 cm rounded area of lucency in the same location as a bipartite patella and is believed to be due to incomplete fusion of the patellar ossification centers [Figure 5].[9] Another potential etiology is that it is due to traction at the insertion of vastus lateralis. Occasionally, this lesion may be symptomatic.[7]
