T2 signal with surrounding bone marrow edema, and a low signal on T1 (Figures 2 and 3). The findings were consistent with a Brodie abscess with surrounding osteomyelitis and a possible septic ankle.

T2 signal with surrounding bone marrow edema, and a low signal on T1 (Figures 2 and 3). The findings were consistent with a Brodie abscess with surrounding osteomyelitis and a possible septic ankle. Furthermore, there was rim enhancement with gadolinium contrast, making an abscess more likely than a tumor (Figure 3).

The talus was then drilled through a nonarticular region with a 2.0 mm drill under fluoroscopic guidance, aiming in a posterolateral trajectory, resulting in an egress of purulent fluid which was sent for Gram stain and culture (Figure 4).
