Healing fibrous cortical defect and a cortical desmoid tumour

Case contributed by Dr Lee-Anne Slater

Presentation

Patient reported a history of bone lesions in his femur when presenting to ED with pain in the right leg post minor trauma.

Patient Data

Age: 22
Gender: Male

On the lateral aspect of the distal right femur in a cortically based position, there is a sclerotic lesion with a well defined margin and no aggressive features. On an X-ray that the patient had printed out from 2 years earlier this same lesion was seen to be more lucent with features of a fibrous cortical defect. Given the previous images the findings were now consistent with a healed fibrous cortical defect.

A irregular bone lesion at the cortex of the medial femoral condyle was also noted. The position and features of this lesion were in keeping with a tug lesion, a cortical desmoid tumour.
