21 paź 2024 · A perforated appendix is one of the complications of acute appendicitis. When appendicitis is left untreated, necrosis (gangrene) of the appendiceal wall can occur and progress to a focal rupture.
28 wrz 2024 · Appendicitis is frequently caused by obstruction of the appendiceal lumen. The appendix continues to secrete mucus which raises intra-luminal pressure causing ischemia, initially antimesenteric, and subsequent gangrene and perforation. Stasis also causes bacterial overgrowth and gas formation.
This review aims not only to define the diagnostic criteria for appendicitis in different imaging modalities (ultrasonography, computed tomography, and magnetic resonance imaging), but also to explain the diagnostic protocols, atypical presentations, and other conditions that can mimic appendicitis.

The vermiform, edematous appendix markedly lengthens with its distal tip extrinsically abutting the right lower renal pole region. No appendicoliths or fecoliths or gross lymphadenopathy. Mild right iliac fossa free fluid is noted accompanied wit...
1 wrz 2020 · The presence of air outside the appendix is a classical finding of perforated appendicitis. A tip to identify perforation in the absence of extra-luminal air is to carefully look for an interruption of the wall, either using colour flow Doppler or on enhanced CT: focal loss of vascularization or enhancement suggests perforation.
Laboratory results, RLQ tenderness, and US findings are congruent with appendicitis. The wall changes and surrounding fluid suggest necrosis/gangrene and presage perforation. An urgent operation was performed which found: perforated appendicitis. appendix, cecum and terminal ileum conglomerate inflammatory mass.
10 sty 2016 · Abscess and extraluminal air are the most specific findings for perforated appendicitis, but have low sensitivity. Periappendiceal inflammatory stranding and focal defect in the enhancing appendiceal wall are more sensitive, but less specific.
