Acute purulent salpingitis in a 62-year-old woman with sigmoid colon diverticulitis. (a, b) Axial T2-weighted images show a distended left fallopian tube with low to intermediate signal intensity content (white arrows); posteriorly the tube is not separable from the sigma, presenting multiple diverticular formations (white arrowhead in a). (c) Axial contrast fat-suppressed T1-weighted image shows marked enhancement of tubaric wall (white arrow) and surrounding fat tissue (white arrowhead). (d) Axial DW image (b = 800 s/mm²) and (e) corresponding ADC map show that the lesion’s content demonstrates restricted diffusion with high signal intensity (white arrow) on DWI image and low signal intensity (black arrow) on ADC map, a finding consistent with a purulent content. (f) Histological sample showed purulent material and many leukocytes in the lumen of the tube and confirmed the presence of mucin-containing regular columnar epithelium lining a mucinous cystadenoma (H&E 300X)
