Case Details

There is a round area with a paucity of trabeculae in the midportion of the calcaneus that looks like a bone cyst

Answer

Diagnosis: CALCANEAL PSEUDOCYST

Calcaneal pseudocyst is the most likely diagnosis.  These are very common normal variants in children and are simply due to paucity of trabeculae in that location.  The other two possibilities include lipoma (a very rare bone tumor) and simple bone cyst.  These are excluded when one looks at the tangential view.

Second view of the calcaneus demonstrates that there is in fact no cyst or mass present.
