Sigmoid diverticulitis complicated by intramural abscess
Sigmoid diverticulitis Sigmoid diverticulitis complicated by an intramural abscess is a severe form of diverticulitis, where inflammation and infection of the diverticula (pouches in the wall of the colon) progress to form an abscess within the colon wall. This is a complex and potentially dangerous condition requiring prompt diagnosis and treatment. -------------------------------------------------------------------------------- 1.
