Imaging of Hidradenitis Suppurativa and Its Complications

Figure 8

Frontal radiograph of the right hand shows focal periarticular soft tissue swelling at the proximal interphalangeal joint of the 2nd digit (thick arrow), suspicious for dactylitis. A small juxta-articular erosion is also noted at the middle phalanx of the middle finger (white arrow), which may represent the arthropathic changes related to HS.
