Figure 4: A coronal proton density MR with fat suppression obtained at the level of the posterior tibia and fibular head demonstrates a mixed intensity lesion (black arrow) within the tibiofibular joint adjacent to the synovium. Signal characteristics confirm that this is an ossification and not simply a calcification. A linear area of hyperintensity within the joint space represents a small joint effusion (white arrow). Also noted is high signal intensity within the fibular head (white arrowhead) indicative of edema, consistent with a bone bruise. This patient also had a sprain of the tibialis posterior tendon, not shown.
Figure 3: Oblique radiograph of the knee. In this figure, the tibiofibular joint space is better demonstrated. The rounded density is again identified (black arrow). Also note degenerative osteophytosis of the superior aspect of the fibular head (white arrow).
