there is relatively diffuse moderate increased T2 signal intensity identified through the talar dome. This is the most prominently seen along the more medial and posterior aspect of the talar dome, however, dies involve a relatively broad area. The appearance is in keeping with bone marrow edema.
There is a focal are of irregularity involving the articular cortex in the far medial aspect of the talar dome. There is a focal cortical irregularity involving the far medial aspect of the talar dome. The irregularity is measuring approx. 0.5 cm. There is slight altered signal intensity in the subcortal marrow.. There is a flake like curvilinear density projected over the joint margin just above this level. This may represent a small ossific fragment. The differential diagnosis for the above described findings would inclide bone marrow edema related to an osteochondral impaction injury. Osteochdritis seddicans may be a consideration, however, given the relatively broad, diffuse area of edema i would have expected to see more subcortical change for this to be the case. This, however, is still within the differential diagnosis.
The report describes degenerative changes of the bones forming the ankle joint associated with inflammation which could result from external injuries or from a few primary bone conditions. It would be best to have this evaluated by an orthopedician for an accurate diagnosis and appropriate management.
Hope this is helpful.
