Imaging of Hidradenitis Suppurativa and Its Complications

Figure 1

Axial FSE T2-weighted fat-suppressed image at presentation shows complex right gluteal subcutaneous collections with heterogeneous high T2-weighted signal intensity and low T1-weighted signal intensity (not shown). The tubular collections (white arrows) are reminiscent of branching primary and secondary sinus tracts and probably represent the chronic phase of these suppurative inflammatory tracts, extending to the deep right ischiorectal and ischioanal spaces. Bilateral dermal thickening and induration are seen. Bilateral enlarged inguinal lymph nodes are also demonstrated ().
