Abscess formation by Salmonella species is an uncommon but significant manifestation of salmonellosis. These localized infections can serve as sources for hospital outbreaks. Appropriate isolation measures and management require early recognition. Three patients with Salmonella abscess were admitted to hospital with a diagnosis other than Salmonella infection. In two, admitted with diagnoses of cholelithiasis and acute appendicitis, respectively, postoperative Salmonella infections developed. A third was diagnosed as having traumatic epididymitis, but was found to have Salmonella orchitis. Appropriate antibiotic therapy was effective in two of the three instances; the other resolved spontaneously. There were no recognized nosocomial infections related to these patients, in spite of delayed diagnosis and treatment. Proper routine wound care plus handwashing after patient contact can minimize the spread of these organisms from unsuspected infections.

The differential diagnosis of left lower quadrant abdominal pain in an adult man includes, among others, sigmoid diverticulitis; leaking abdominal aortic aneurysm; renal colic; epididymitis; incarcerated hernia; bowel obstruction; regional enteritis; psoas abscess; and in this rare instance, situs inversus with acute appendicitis. We report a case of situs inversus totalis with left-sided appendicitis and a brief review of the literature. There were several subtle indicators of total situs inversus present that were missed by the physicians and surgeons who initially evaluated the patient prior to surgery. Computed tomography scan with contrast, however, revealed the diagnosis immediately, and treatment was successfully initiated.

Several conditions can clinically mimic renal colic. We assessed the accuracy of non-contrast-enhanced helical CT and of ultrasonography (US) in offering an alternative explanation for flank pain. In a 3-year period, 181 patients with acute flank pain underwent US and non-contrast-enhanced helical CT in a blinded sequence. Their efficacy in detecting both alternative causes of pain and additional findings unrelated to the pain was assessed in 160 cases with a confirmed diagnosis. An alternative cause was found in 23 cases (14%). US gave 4 false-negative results (1 acute appendicitis, 1 ovarian cyst torsion, 1 diverticulitis, and 1 papillary necrosis) and 2 false-positive results (1 acute pyelonephritis and 1 diverticulitis), with a 78% sensitivity and a 98% specificity for nonlithiasic causes. CT gave 5 false-negative results (1 complicated ovarian cyst, 1 pleuritis, 1 epididymitis, 1 acute pyelonephritis, and 1 papillary necrosis) and 1 false-positive (1 simple ovarian cyst described as a complicated lesion), resulting in a 74% sensitivity and a 99% specificity for diagnosing alternative causes. There were 130 additional US findings in 68 patients and 151 additional CT findings in 77 patients. A wide spectrum of findings can be identified in subjects imaged for flank pain. Non-contrast-enhanced helical CT and US have comparable accuracy in diagnosing causes other than stone disease.

A 35-year-old patient with hemophilia A presented with rapidly progressive polyarteritis nodosa (PAN). He had been infected with hepatitis B virus (HBV) by repeated transfusion and was positive for hepatitis B surface antigen but negative for hepatitis B surface antibody. The patient presented symptoms of acute epididymitis followed by emergency admission because of acute appendicitis. On day 7 of admission, he complained of severe back pain, and computerized tomography (CT) showed massive perirenal hematoma. On day 49, mild monoplegia in the left arm suddenly developed, and CT and magnetic resonance imaging revealed multiple cerebral infarctions. Factor VIII replacement therapy was attenuated; however, cerebral infarction was progressive and extended throughout the cerebral hemispheres. He was diagnosed with classic polyarteritis nodosa (cPAN), and pulse methylprednisolone was continued. The patient died of supratentorial herniation, and autopsy revealed that vasculitis associated with intimal thickening was present in the liver, pancreas, intestine, kidneys, and larger-sized cerebral arteries. The development of cPAN appeared to have originated from chronic HBV infection, and this is the first report of cPAN in hemophilia patients. Concomitant hemorrhagic and thrombotic manifestations of cPAN are hardly treatable in patients with coagulation disorders, and the current case may represent a rare transfusion-related complication in hemophilia patients.

Acute appendicitis often presents as right lower quadrant (RLQ) pain, severe tenderness at the point of McBurny or Lanz, and Blumberg's sign. Scrotal events with appendicitis are very rare. In our case, a 63-year-old Japanese man presented with severe RLQ pain and high fever. Physical examination revealed severe tenderness (including both points of McBurny and Lanz) and Blumberg's sign. The scrotum was slightly swollen and showed local heat with severe testicular pain. Abdominal computed tomography revealed ascites in a pelvic space and the right side of the spermatic cord was swollen. Emergency operation was performed and the final diagnosis was catarrhal appendicitis and acute epididymitis. This is the first report of acute appendicitis concomitant with acute epididymitis.

An ectopic ureter draining into the seminal vesicle or vas deferens in males is a very rare anomaly and is usually associated with renal dysplasia or agenesis. An ectopic ureter associated with a dysplastic kidney is not usually a suspected cause during clinical evaluation of children with abdominal pain. This report presents a rare case of an ectopic ureter associated with a dysplastic kidney with an acute infection in a previously healthy 12-year-old boy, demonstrated by magnetic resonance imaging. He presented with abdominal pain that mimicked acute appendicitis-like symptoms which was subsequently complicated by epididymitis manifesting as an acute scrotum. Clinicians should consider including an ectopic ureter in the differential diagnosis of children presenting with acute abdomen.
