Terminal ileal diverticulitis

One month of acute abdominal pain with one day of multiple episodes of vomiting and shivers. painPain more localized at the right iliac fossa.

The locality of the outpouching (diverticuli(diverticula) at the right iliac fossa's terminal ileum unequivocally rules in Meckel's diverticulitis as the cause of the excruciating right lower abdominal quadrant pain/ acute abdomen in the patient but with concomitant terminal ileitis. The narrow-necked bowel bulges appearedappear superiorly located however, belowand lie roughly 1 cm beneath the right rectus sheath musculature about one centimetres from below. The appendix, which could have resulted intoin the right lower quadrant pain, looked normal.

MultiThere are multi-focal (at least two identified) small bowel out-pouchings at the terminal ileum at the right iliac fossa, the largest of which is medial in location and measuring 0.969.6 x 0.42 cm4.2 mm in size, is noted. The out-pouchings (diverticula) showsshow mild oedematous wall changes plusand relatively augmented vascular signals on color Doppler evaluation with surrounding echogenic reactedreactive omental fats wrapped round-aboutfat surrounding their peripheral margins in keeping with an inflammatory process (diverticulitis).

Gut signature is maintained within the diverticulidiverticula with no obvious perforationsperforation. The terminal ileum exhibitexhibits diffuse mucosal layers thickening consistent with terminal ileitis, but with maintained Kerckring folds (piano keyboard appearance). The appendix (well visualized extrinsically over the ipsilateral right iliopsoas muscle belly) showshows no inflammatory changes or appendicolith and measures 0.42 cm4.2 mm in diameter.

What is the other possible cause of pain atwithin the right lower abdomen that clinically presents as Meckel's diverticulitis but is more common than Meckel's diverticulitis?
