Retrospective analysis of computed tomography examinations in patients with lower abdominal pain: A single-center experience

Figure 1 Contrast-enhanced coronal computed tomography images of a 34-year-old woman at 19 weeks gestation presenting with right lower quadrant abdominal pain. Images demonstrate an enlarged appendix (approximately 7 mm in diameter) with fecal stones located adjacent to the gravid uterus (orange arrow), consistent with acute appendicitis in pregnancy (blue arrow).

Figure 2 Contrast-enhanced coronal computed tomography images of a 57-year-old male with left lower quadrant abdominal pain demonstrating situs inversus totalis. The liver and appendix are visualized in the left abdomen. The appendix is swollen at its root (approximately 1 cm in diameter) with high-density fecal material, indicative of acute appendicitis associated with complete visceral inversion. Orange arrow: Inflamed appendix arising from the cecum in the left lower quadrant. The appendix is filled with contrast and shows distal swelling up to 9 mm in diameter; Blue arrow: Inverted position of the liver on the left side of the abdomen, indicating complete visceral inversion.

Figure 3 Contrast-enhanced coronal computed tomography images of a 44-year-old woman presenting with lower abdominal pain and fever, showing evidence of intestinal malrotation with abnormal positioning of the superior mesenteric artery (white triangle) and superior mesenteric vein (white arrow). Perforated acute appendicitis (orange arrow) is identified within an abnormally positioned cecum, resulting in the formation of a midline pelvic abscess (blue arrow).
