A 5-year-old boy admitted with localized lower abdominal pain and tenderness simulating acute appendicitis underwent surgery, and primary omentitis without appendicitis or other cause of an acute abdomen was diagnosed. The absence of other concomitant signs and symptoms of acute abdomen was remarkable. This is the first case of primary omentitis as a cause of acute abdomen in the English-language literature.

A giant appendix is an extremely rare and improbable finding during surgery in suspected cases of acute appendicitis. Although this condition is primarily suggestive of neoplasia, it is usually due to an inflammatory or infectious disease. We report a case of Crohn's disease limited to the appendix, which was diagnosed after a short right ileocolectomy. Only 156 similar diagnoses have been reported in the literature to date. This disease appears to have a benign course and therefore differs from classical Crohn's ileocolitis. For this reason, these patients do not require any specific investigation or follow-up.

We present the first case, to our knowledge, of a patient with a CT diagnosis of acute appendicitis strangulated in a femoral hernia, a known but very rare entity. CT features of acute appendicitis within the hernia established the correct diagnosis. The pathological findings confirmed the diagnosis of this rare location of appendicitis.

A 20-year-old African female was hospitalized several times for diffuse chronic abdominal pain. The following exclusions were made: Acute adnexitis (by laparoscopy), acute appendicitis (by appendectomy), gastric ulcerations (by esophagogastroduodenoscopy) as well as Crohn's disease and ulcerative colitis. However, once taking a closer microscopical look at the mucosa, that otherwise appeared colonoscopically to be normal, multiple eggs of schistosomiasis mansoni (S. mansoni) were found in the colon as well as the rectum. Thus, the diagnosis of an intestinal bilharziosis was finely established. In retrospect even the sample taken for the appendix could have indicated this diagnosis already earlier on. Both the antibodies (ELISA/IFAT) and the specific immunoglobulins (IgE) for S. mansoni proved significantly positive. Therapy of choice was a single oral dosage of praziquantel. Migration and tourism have considerably increased the range of tropical and infectious diseases that need to be included into differential diagnosis. This case report focuses on intestinal bilharziosis as a potential underlying cause of chronic abdominal pain in immigrants of endemically affected areas. Direct diagnosis is the most important diagnostic method. The adult worms are usually inaccessible, so the method of choice to assess both diagnosis and the degree of activity of a chronic infection is evidence of living eggs in the stool. Alternatively, in case of lack of direct evidence diagnosis can be established by endoscopy and rectal biopsy.

The authors describe a case with a rare diagnosis of adenocarcinoma of the appendix in an adult female patient. The patient was indicated for surgical revision on account of acute appendicitis with a peroperative finding suspect of malignity of the vermiform appendix. A radical resection of the ileocoecal area was performed along with part of the ascendant colon and appropriate mesocolon as a primary operation. According to the postoperative histological evaluation of the resected portion the diagnosis of adenocarcinoma of the appendix was confirmed.

Schistosomiasis is a widely prevalent disease in the world and usually involves the gastro-intestinal and urinary tract. The involvement of the female genital tract has been well-established in S. haematobium infections and is rare with S. japonicum infections. This case involves a Filipino female who was admitted to the University Hospital Kuala Lumpur for right iliac fossa pain and was diagnosed initially as acute appendicitis. Ultrasound showed a multi-septated pelvic cyst leading to a provisional diagnosis of ovarian torsion. Intraoperatively a right parovarian cyst was detected and removed. Histology revealed a congested cyst wall with areas of haemorrhage with several viable and calcified eggs of S. japonicum measuring 85 microns x 62 microns. Within the cystic cavity blood admixed with eggs were seen. Confirmation was carried out by using the indirect haemagglutination (IHA) test. This is a first report of upper genital schistosomiasis mimicking an ovarian tumour.

By 1996, the median survival of patients with cystic fibrosis (CF) in North America had increased to 31 years. With the markedly improved life expectancy, many CF patients are now adults. There is an associated increased risk of certain colonic disorders, and the emergence of other previously unrecognized disorders, in adult CF patients. The distal intestinal obstruction syndrome (DIOS), which is more common in older patients, is a frequent cause of abdominal pain. Intussusception may complicate DIOS; other differential diagnoses include appendiceal disease, volvolus, Crohn's disease, fibrosing colonopathy and colonic carcinoma. The diagnosis of acute appendicitis, although uncommon in patients with CF, is often delayed, and appendiceal abscess is a frequent complication. The prevalence of Crohn's disease in CF has been shown to be 17 times that of the general population. Right-sided microscopic colitis is a recently recognized entity in CF of uncertain clinical significance. Fibrosing colonopathy has been confined mostly to children with CF, attributed to the use of high strength pancreatic enzyme supplements, but it has been reported in three adults. Nine cases of carcinoma of the large intestine have been reported worldwide, associated with an apparent excess risk of digestive tract cancers in CF. Despite high carrier rates of Clostridium difficile in patients with CF, pseudomembranous colitis is distinctly rare, but severe cases complicated by toxic megacolon have been reported. In these patients, watery diarrhea is often absent. Adult CF patients with refractory or unexplained intestinal symptoms merit thorough investigations.

The authors describe the case-histories of three pregnant patients with acute appendicitis treated laparoscopically. They present a brief account of laparoscopic appendectomy in pregnant women and demonstrate on the described cases its advantages and safety.

Using the method of graded compression the author examined by ultrasonography a total of 1318 patients with an equivocal clinical finding of acute appendicitis. In patients where finally appendicitis was not verified a wide spectrum of other diseases was detected including gastrointestinal (n = 406), biliary (n = 12), gynaecological (n = 72), urological (n = 12) and other (n = 7) pathological conditions using sonography. Sonography is a useful differential diagnostic modality which makes it possible to visualize diseases which clinically imitate appendicitis.

Our objective was to assess the ability of MR imaging in the detection of the normal appendix, and to describe the MR appearance of the normal appendix. There were 15 healthy volunteers (11 girls, 4 boys; mean age 12.3 years) who underwent MR imaging on a 1.0-T unit. The imaging protocol included axial and coronal T2-weighted ultra turbo spin-echo (UTSE)-weighted images, axial T1-weighted turbo spin-echo (TSE) and coronal short tau inversion recovery (STIR)/TSE sequences. Confidence regarding the detection was scored from 1 (high confidence) to 3 (low confidence). Thickness was measured and MR appearance described. Clinical control after 2 weeks revealed no signs or symptoms of acute appendicitis. The normal appendix was seen in 86% on T2/UTSE-weighted images and in 73% on T1/TSE-weighted images and in none on STIR/TSE images. On axial T2/UTSE-weighted images, normal appendix had a hyperintense center and a hypointense wall, and was mostly hypointense on T1/TSE-weighted images, with a mean thickness of 4.5 mm. Magnetic resonance imaging seems to be an accurate method for the assessment of the normal appendix in children; thus, MR imaging might be an alternative to CT if US examinations are inconclusive.
