Two cases of infection of the right THA of a 65-year-old female (AC) and the left THA of a 73-year-old male (DF). Coronal STIR (A) image shows pericapsular edema (white arrowheads) and femoral periprosthetic bone edema (arrows). Axial T1-weighted (B) and axial T2-weighted (C) images show a sinus tract that communicates with the skin (black arrowheads). Increased number and size of loco-regional inguinal lymph nodes (void arrows, B) can be observed too compared to the contralateral side. Coronal STIR (D) and axial T2-weighted (E) images show a periprosthetic fluid collection (arrows) with the sinus tract up to the skin (arrowheads). Also note lamellated synovitis (curved arrow) anterior to the prosthetic neck on axial T2-weighted image (F) and enlarged loco-regional iliac lymph nodes on coronal STIR image (void arrows, D)
