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.

Pulsation artifact. A 31 year old male with right knee pain. Axial T1W MRI image shows a low signal rounded focus (arrow) in fibula, which is caused by pulsation artifact from popliteal artery (arrowhead) and mimics a tumor

Mentions: Pulsation of vascular structures can cause “ghosting” on MRI.[49] This can mimic bone lesions as artifactual image data from the vessels are superimposed onto bone [Figure 27]. Repeating the imaging sequence after swapping the phase- and frequency-encoding directions can help to determine whether or not the lesion is real. To reduce pulsation artifact, one can place a saturation band over the vessels or not align the vessel and target lesion in the same phase-encoding direction.[50]
