What is pseudodiverticulae?

Pseudodiverticulae are small outpouchings that occur on the colon wall. They are referred to as "pseudo" because they are not true diverticula, which are formed by protrusions of all layers of the bowel wall. Instead, pseudodiverticulae are formed by the herniation of mucosa and submucosa through weakened areas of the colonic wall, such as areas of vasculitis, inflammation, or ischemia.

Pseudodiverticulae are typically seen in patients with inflammatory bowel disease, such as ulcerative colitis or Crohn's disease. They can also occur in patients with diverticulitis or cancer of the colon.

Although pseudodiverticulae are not true diverticula, they can still cause complications such as bleeding or perforation. Treatment may involve managing the underlying condition, such as controlling inflammation with medication or surgical removal of the affected section of the colon.
