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.

Humeral pseudocyst. A 47 year old female with left shoulder pain. A round radiolucency in the greater tuberosity (arrow) on the external rotation shoulder radiograph (A) corresponds to normal fatty marrow (arrow) which is hyperintense on the (B) T1W and hypointense on the (C) T2W fat-saturated coronal MRI images

Figure 2: Humeral pseudocyst. A 47 year old female with left shoulder pain. A round radiolucency in the greater tuberosity (arrow) on the external rotation shoulder radiograph (A) corresponds to normal fatty marrow (arrow) which is hyperintense on the (B) T1W and hypointense on the (C) T2W fat-saturated coronal MRI images

Mentions: A radiolucent area in the humeral head may be seen due to a normal decrease in the trabeculae often associated with an increase in the amount of fat.[6] This radiolucency is seen in the superolateral humeral head and may be misdiagnosed as a chondroblastoma, giant cell tumor, Langerhans cell histiocytosis, or even an osteolytic metastasis on radiographs.[7] The increased fat in this region can be readily seen on MRI and helps make the diagnosis [Figure 2]. On radiographs, this pseudolesion will be seen on an external rotation view of the shoulder and there is usually a sharp line of demarcation inferiorly between the pseudolesion and adjacent marrow, which is due to the line of fusion between the epiphysis in the greater tuberosity and the shaft of the humerus. The remainder of the margin is usually ill-defined.[6]
