Purpose: To evaluate the accuracy of limited computed tomography (CT) in the hands of the average radiologist in a busy community hospital assessing a patient for acute appendicitis. Materials and methods: Ninety-six consecutive patients were examined with CT and the results, independently reported, were correlated with histopathologic findings and clinical followup. Results: Forty-three patients had acute appendicitis, 53 patients did not; sensitivity was 89 %, specificity 91 %, accuracy 90 %, positive predictive value 91 %, and negative predictive value 90 %. Nonvisualization of the appendix did not necessarily preclude an accurate assessment for acute appendicitis. Conclusion: Limited CT of the pelvis using rectal contrast only is a useful radiographic test for evaluating acute appendicitis, with practical application for the average radiologist in a busy community hospital.Keywords Acute appendicitis ± Computed tomography ± Abdominal pain ± Acute abdomen ± Appendix The examinations were performed using GE Advantage HiSpeed Emergency Radiology (2001) 8: 257±261 Ó Am Soc Emergency Radiol (ASER) 2001 1-2 54-7 24 24 12 Fax: + 1-2 54-7 24 05 02Fig. 1 Supine view, normal appendix (arrow)

“…Some studies suggest mortality rate for elderly patients with appendicitis is about 15%. 15 The diagnosis of acute appendicitis might also be delayed in the elderly where some of the differential diagnosis should also be considered. These include right-sided diverticulitis, caecal carcinoma, Crohn's colitis, mesenteric inflammation, complicated ovarian cysts, endometriosis, ectopic pregnancy, local lymphadenopathy, fibrofatty proliferation, Tuboovarian abscess, epiploic appendicitis, biliary colic and urinary tract infection.…”

Background: Acute appendicitis is the most common cause of acute abdominal pain in young adults requiring emergency surgery. Appendicectomy is the most frequently performed surgery. The diagnosis is often challenging and the decision to operate in an emergency setting is always debatable. A combination of clinical signs and symptoms with laboratory findings in many scoring systems are suggesting the probability of appendicitis and the possible subsequent management pathway. The aim was to evaluate accuracy of the clinical Alvarado scoring system, radiological finding and histopathological examination for the diagnosis of acute appendicitis.Methods: A retrospective study was conducted in the department of general surgery in a tertiary care centre in South India. Total of 237 patients with acute abdominal pain were included and evaluated with the clinical Alvarado scoring system, radiological finding with (USG/CT abdomen) and histopathological examination for the diagnosis of acute appendicitis. The data was collected and analyzed retrospectively.Results: Of the 237 patients, 164 patients were male (69.1%) and rest is female. The correlation of the Alvaroda score with histopathological findings in groups with score > 7 and ≤7 the correlation of Alvarado score and the ultrasound findings were comparable between the study groups. The sensitivity of ultrasound in diagnosing acute appendicitis in patients with Alvarado score >7 was 72.99%. The sensitivity of ultrasound in diagnosing acute appendicitis in patients with Alvarado score ≤7 was decreased to 27%.Conclusions: The diagnostic accuracy of clinical features is far better than radiological investigations in the diagnosis of acute appendicitis. Therefore, it is concluded that it is better to use radiological investigations only to confirm the diagnosis of acute appendicitis rather to diagnose it.

“…More broadly, our series is a reminder that not all appendiceal changes detected at CT are due to acute appendicitis. Other described causes of appendiceal dilatation and peri-appendiceal fluid include a wide variety of inflammatory and neoplastic processes such as Crohn’s disease, mucocele of the appendix, peri-appendicitis, adenocarcinoma or other tumors of the appendix, and ischemia [1,5–8]. It should also be remembered that appendiceal diameter is variable, and a diameter over 6 mm has been reported to occur in up to 42% of normal appendixes, either with visible or indiscernible content [9].…”

Computed tomography findings mimicking appendicitis as a manifestation of colorectal cancer

et al. 2009

The primary computed tomography (CT) signs of appendicitis can also be seen with other inflammatory or neoplastic processes. We report on two cases in which appendiceal dilatation and peri-appendiceal fluid or stranding were the dominant imaging manifestations of colorectal carcinoma in the ascending colon. This study highlights the need to closely examine the ascending colon in patients with a suspected CT diagnosis of acute appendicitis, since these findings may be secondary to an inconspicuous colorectal carcinoma.
