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.

Avulsive cortical irregularity of the posterior femur. An 18 year old female with left knee pain. (A) Lateral radiograph of knee demonstrates an area of cortical irregularity at the medial aspect of the distal femoral metaphysis (arrow) (B) Corresponding axial T2W fat-saturated MRI image shows marrow edema (arrowhead) at the area of cortical irregularity (arrow)

Mentions: An avulsive cortical irregularityof the posterior femur, known as a cortical desmoid, appears as an irregular focal radiolucent lesion along the posteromedial aspect of the distal femur in children [Figure 7].[13] Differential diagnosis for this appearance includes osteomyelitis and surface osteosarcoma, especially if the lesion has an aggressive appearance. It has been proposed that this lesion may be caused by traction due to the medial head of gastrocnemius or adductor magnus.[14] This lesion should not be seen in skeletally mature individuals.
