Benign Bone Lesion – Enchondroma

 

There is an enchondroma seen in the left femoral shaft on this Hologic left proximal femur radiograph.

On the accompanying radiograph, the lesion was read as an enchondroma.

Case Description:

The DXA image shows a left Hologic proximal femur scan with an enchondroma in the left femoral shaft. The accompanying radiograph was read as an enchondroma. An enchondroma is a cartilage cyst found in the bone marrow. Enchondromas have a characteristic appearance on MRI scanning. An enchondroma may have increased uptake on a PET scan.
