Radiographs of the left leg confirmed subcutaneous emphysema consistent with necrotizing fasciitis (Figure 1).
Axial CT images with IV contrast of the lower pelvis (a and b) demonstrating extensive subcutaneous emphysema consistent with necrotizing fasciitis around the left femur (short arrows). Note the air filled abscess cavity (b) filled along the posterior aspect of the left hip (long arrow).

This further confirmed the necrotizing fasciitis (Figures 2(a) and 2(b)) but also identified a collection in the presacral space (Figure 3) that communicated to the left leg through the left sciatic notch, which is consistent with an AL.
