- Abstract
Diverticular disease of the colon is a common entity in the Western world with a prevalence ranging from approximately 10% in adults younger than 40 years of age to 50-70% among patients older than 80 years with no gender predilection.[1] The sigmoid colon is the most commonly affected segment and in 2% of patients with diverticulitis there may be fistulous communication with neighbouring structures.[2] This case reports a giant pneumosalpinx secondary to a fistulous communication of the fallopian tube with a sigmoid diverticulum. The histology confirmed a hydrosalpinx, complicated by areas of fibrosis and inflammation, consistent with the clinical impression of a pneumo/hydrosalpinx communicating with a sigmoid colon diverticulum (Appendix S1). Giant colonic diverticulum, defined as a diverticulum 4 cm or larger[[5]] is a rare manifestation of diverticular disease, with 90% of the cases being associated with sigmoid diverticulosis.[7] Although the exact pathophysiology that causes these diverticula to grow is unknown, the most commonly accepted theory is that the fibrous neck above the opening of the diverticulum acts as a "ball valve" which allows air entry but prevents its exit.
