Terminal ileal diverticulitis in disguise

Acute Ileal Diverticulitis: Computed Tomography and Ultrasound Findings

“…Therefore, most patients were diagnosed as acute appendicitis initially. These were similar to the result of previous studies [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 10 , 13 , 14 , 15 , 23 ]. Preoperative misdiagnosis of this disease results in emergent surgery with or without postoperative complications.…”

“…The technological advances and widespread use of CT have enabled radiologists to play an essential role in diagnosing acute ileal diverticulitis [ 3 , 16 , 18 ]. The characteristic CT findings of acute ileal diverticulitis in this study included ileal wall thickening with small-sized inflamed diverticulum at the mesenteric side and surrounding mesenteric fat infiltration, which was consistent with CT findings in previous studies [ 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 13 , 16 , 18 , 24 , 30 ]. Especially, direct visualization of the inflamed diverticulum was the key feature in diagnosing acute ileal diverticulitis.…”

“…Non-Meckelian jejunoileal diverticula are rare, acquired false diverticula, with reported incidence rates of 0.5% to 2.3% on small bowel contrast studies [ 12 , 31 ]. Considering that approximately 20% of jejunoileal diverticula occur in the ileum and only 10% of them develop complications, acute ileal diverticulitis is an extremely rare disease despite it being the most common complication of ileal diverticulosis [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 23 , 24 ]. Our hospital, which has a total of 836 beds, including 80 beds allocated to surgical wards, collected a total of 17 cases over a 15-year period, further demonstrating the rarity of this condition.…”

“…Preoperative misdiagnosis of this disease results in emergent surgery with or without postoperative complications. With the widespread use of CT and US in the evaluation of patients with acute abdominal pain [ 3 , 4 , 5 , 6 , 7 , 9 , 11 , 16 , 20 , 21 , 22 , 32 , 33 ], it has been important to recognize the CT and US findings of acute ileal diverticulitis and to include them in the differential diagnoses because this disease is often not suspected clinically.…”

“…Acute ileal diverticulitis is a very rare disease that often presents as acute right lower quadrant pain in elderly patients, and it is usually misdiagnosed as acute appendicitis [ 1 , 2 , 3 , 4 , 5 , 6 , 7 ]. With a low prevalence and nonspecific symptoms, an accurate preoperative diagnosis was seldom made, which resulted in a high mortality rate of 25–50% [ 8 , 9 , 10 , 11 ].…”
