Dünndarmdivertikel

Dünndarmdivertikulitis
mit Perforation und Abszess. Links oben zahlreiche Divertikel des Dünndarms, an dieser Stelle reizlos. Links Mitte deutliche Wandverdickung weiter kaudal gelegener Dünndarmabschnitte. Links unten große Abszessformation (ca. 7 cm) zwischen den Dünndarmschlingen auf Beckeneingangsebene ventral. Rechts oben koronare Darstellung von Dünndarmdivertikel links im Bauch ohne Perforation, im Mittelbauch Abszessformation mit deutlich entzündlich veränderten angrenzenden Dünndarmschlingen. Rechts unten Z.n. Drainage der Abszessformation, bei der ca. 50 ml Pus abgezogen werden konnten.

gastrointestinal bleeding from jejunal diverticulum with an occult Dieulafoy’s lesion. Coronal (upper) and axial (lower) images. The amount of intraluminal contrast increases in diverticular (black arrowhead) and jejunal (black arrow) lumen in comparision with arterial phase. Hyperattenuating material in the colon suggests blood (white arrowhead).

Jejunoileal diverticula, also referred to as jejunal diverticula or diverticulosis as most of the diverticula are located in the jejunum, are outpouchings from the jejunal and ileal wall on their mesenteric border that represent mucosal herniation through sites of wall weakening .

Jejunoileal diverticulitis is much rarer than colonic diverticulitis.
