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.

Calcific tendinitis (resorptive phase). A 47 year old male with left thigh pain. (A) Axial and (B) coronal CT images show calcifications at the insertion site of the gluteus maximus tendon to the posterior femur (arrow). Mild cortical erosion is also noted at the gluteal insertion site (arrowhead)

Mild cortical erosion is also noted at the gluteal insertion site (arrowhead)

Mentions: Calcific tendinitis is a common cause of joint pain and stiffness, and is caused by the deposition of calcium hydroxyapatite crystals in the tendons.[40] The tendons of the rotator cuff and around the hip [Figure 20] are most commonly involved; however, it can involve any tendon.[41] During the resorptive phase, calcific tendinitis can mimic an aggressive process such as infection or neoplasm.[42] Calcific tendinitis can be associated with erosions of the adjoining bone, mimicking a destructive bone lesion. This aggressive pattern is common along the posterior proximal femoral diaphysis. The process is typically self-limiting, but needle barbotage and steroid injection can provide symptomatic relief.[42]
