An infected urachal cyst classically presents with a tender lower midline abdominal mass and systemic signs of infection, including fever, malaise, and leukocytosis. At times, the findings may be clinically confused with those of acute appendicitis, Meckel's diverticulitis, or peritonitis. Sonography aids in differentiating these entities by identifying the localized cystic mass containing debris, located anteriorly in the low mid-abdomen, extending from the region of the bladder to the umbilicus. We present an unusual case of an infected urachal cyst in a 6-year-old boy who presented with lower abdominal pain, fever, intermittent diarrhea, polyuria and dysuria, a firm, fixed left lower quadrant tender mass, and an elevated white blood cell count.

Meckel's diverticulum (MD) has varied presentations and often becomes a diagnostic challenge. The purpose of this study was to review the various presentations of symptomatic MD and to assess the sensitivity of the Meckel's scan as a diagnostic tool in patients with bleeding MD. The hospital records of 71 consecutive patients with a diagnosis of MD from 1990 to 2005 were retrospectively reviewed. The data was assessed for age at presentation, sex, clinical features, investigations performed, surgical intervention and histopathological findings. There were 71 patients with a diagnosis of MD (age 2 days-14 years). In eight patients, MD was an incidental finding at laparotomy. The remaining 63 patients were symptomatic and presented with various clinical features. Ten patients (15.8%) had clinical features of peritonitis; of these, six had perforated MD and four had Meckel's diverticulitis at laparotomy. Nine patients (14.2%) were diagnosed as intestinal obstruction, and at laparotomy, a Meckel's band was found to be the cause of the obstruction. Nine patients (14.2%) had a patent vitello-intestinal duct and presented with umbilical discharge. Thirty-five patients (55.5%) presented with episodes of bleeding per rectum or malaena. Ultrasound scans revealed intussusception in six patients requiring open reduction. Of the remaining 29 patients with bleeding per rectum, 27 underwent a Meckel's Tc99 scan that showed a positive tracer in 18 patients (66.6%) and negative in 9 (33.3%). All patients with a symptomatic MD underwent resection of the diverticulum. Histology revealed ectopic gastric mucosa in 43 patients (68.3%). MD has various presentations and can be easily misdiagnosed. It is necessary to maintain a high index of suspicion in the paediatric age group. The Meckel's scan has a poor positive predictive value and cannot be relied upon for a diagnosis in cases of bleeding MD if Tc99 scan is negative.

A man, aged 74, presented with a rare clinical entity of an acute surgical abdomen similar to acute appendicitis. This case showed a non-Meckel's ileal diverticulitis that was complicated with a diverticular perforation and associated peritonitis. This is a very rare but potential life-threatening surgical emergency, mimicking the clinical presentation of acute appendicitis. The subject of small bowel non-Meckel's diverticulitis is reviewed because of the rarity of this condition and the diagnostic challenges it poses.

Although many people have Meckel's diverticulum, only some experience any symptoms, most under the age of 10. In adults it is usually asymptomatic but approximately 4% develop complications. Meckel's diverticulum is usually diagnosed in the first years of life and after that the risk of the complications decreases with increasing age, with no predictive factors for the development of complications. We describe the case of a 34-year-old man admitted in the emergency department with diffuse abdominal pain, nausea, flatulence and lack of transit for feces and gas. The patient had been previously operated for peritonitis due to a perforated ulcer. Clinical examination and paraclinical investigations (abdominal radiography and ultrasound) suggested the diagnosis of intestinal obstruction, probably produced by adhesions due to previous abdominal intervention. The diverticulum was resected using a linear stapler and the patient recovered without any complications. Small bowel obstruction due to Meckel's diverticulitis may be caused by entangled loop of small bowel around a fibrous cord, intussusception, volvulus, or incarceration within a hernia sac. The discovery of a Meckel's diverticulum complication in a mid thirties patient represented an intra-operatory surprise and is the peculiarity of the case.

A 56-year-old male presented to the hospital with complaint of abdominal pain. On clinical evaluation, the patient had features suggestive of perforation peritonitis. Blood indices revealed leukocytosis, hemoconcentration, and pre-renal azotemia. Relevant CT scan images delineating the pathology have been uploaded. Surgical intervention with small-bowel resection was performed for perforated Meckel's diverticulitis. Post-operative course was uneventful.
