Radiographic Findings and Differential Diagnosis

There is a single broad-based bony excrescence arises from
the medial aspect of the right femoral neck, with trabecular
pattern continuous with the parent bone. Adjacent to the superior
portion of this lesion is a well-corticated lucency with a
very narrow zone of transition. Also, the right femoral neck
is wider than the left, representing likely abnormal remodeling.
No associated soft tissue mass is noted. Note: If dedicated
hip views were obtained, the characteristics of this lesion
could be better identified.
There are a few questions that need to be addressed at this
point. First, what does the bony lesion represent? Second,
what does the adjacent lucency represent? Are these lesions
related, and if so, which one caused the other? Third, what
should we do next regarding imaging? Before we answer this
last question, based on the radiograph, a confident diagnosis
should be obtained. Of the following differential, the following
differential may be considered:
