Bacteria of the genus Pseudomonas occupy diverse environments. The Pseudomonas fluorescens group is particularly well-known for its plant-beneficial properties including pathogen suppression. Recent observations that some strains of this group also cause lethal infections in insect larvae, however, point to a more versatile ecology of these bacteria.

Inguinal canal lipomas are a frequent, often unrecognised finding on abdominopelvic CT. Commonly referred to as spermatic cord or round ligament lipomas, they are not true tumours of fat but are extrusions of extraperitoneal fat into the inguinal canal. Their fat content and shared location in the inguinal canal result in confusion with fat-containing inguinal hernias with which they often coexist.

Background: Achalasia is a disorder of oesophageal motility and is rare in children. The mainstay of therapy has been surgery with its attendant complications and long postoperative stay. Treatment by hydrostatic balloon dilatation, a less morbid procedure, has not found much favour.

Schistosomiasis is one of the commonest parasitic diseases affecting mankind. Egyptian schistosomiasis (mansoni and haematobium) is capable of producing fibrosis and/or calcification, resulting in striking radiological features in target organs. Our two cases with biliary and pancreatic calcification provide a combination of features not documented previously.

A case of pancreatic fistula successfully managed by the endoscopic insertion of an expanding-mesh metal stent into the pancreatic duct is reported. The patient had developed a fistula following rupture of a pancreatic pseudocyst, and attempted transpapillary drainage using plastic endoprostheses had failed due to prosthesis migration. Insertion of a Strecker metal stent was followed by rapid and sustained clinical improvement and cessation of fistula drainage.

In 18 patients, 27 of thirty two pseudocysts were successfully drained percutaneously. The first 26 were drained directly and the last six drained transgastrically. Failures resulted from tube blockage by necrotic phlegmon in three and pancreatico-cutaneous fistulation in two with obstructed pancreatic ducts.

In four out of six gallbladders with schistosomal infestation, calcified granulomas were dense enough to be seen on abdominal radiographs. In one patient, faint calcification seen on a specimen of the excised gallbladder was not visible on the abdominal radiograph. Calcification on abdominal radiographs, especially serpiginous, seen in the region of the neck of gallbladder, appears to be the clue to the diagnosis of gallbladder schistosomiasis in people from endemic areas.

Calcification of the ureters, bladder and seminal vesicles was detected in six patients studied on computed tomography (CT) for evaluation of genitourinary schistosomiasis and in four others examined for intestinal schistosomiasis. Other findings included pyelocaliectasis in ten kidneys, vesical carcinoma in one, seminal vesicle granuloma in one and non-visceral calcification in pelvic tissue in one patient.

Radiologically controlled catheter drainage is now accepted therapy for fluid collections in many parts of the body. While this is performed mainly in the abdomen, the chest is increasingly being drained percutaneously as an alternative to surgical drainage (van Sonnenberg et al 1984; Westcott 1985; O'Moore et al 1987; Crouch et al 1987). This report outlines the experience with 31 chest collections treated by the intervention radiologist over a two-year period.

Schistosomiasis in its many forms still presents a major public health challenge. Its tendency to cause dystrophic calcification makes it ideal for radiologic study. With population movement the disease may be encountered in unexpected countries especially with the sensitivity of CT to the presence of calcium.

Six patients had strictures of the right colon not causing clinical obstruction. The strictures did not fill during barium enema tests resulting in the 'amputated' proximal right colon mimicking the caecum and/or terminal ileum. Positive caecal identification relies on terminal ileal and appendiceal filling.

In a 6-month period, 25 appendices with histological involvement by schistosomiasis were radiographed. Eleven showed varying degrees of radiographically detectable calcification having a spotty, linear, or amorphous pattern affecting either a short segment or the whole appendix. Four of these appendices had a mixed pattern and one also had nodular calcification in the mesoappendix.

The radiological and clinical features of 9 cases of obstructed post-traumatic diaphragmatic hernia are reviewed. In none of these patients was the diagnosis of a diaphragmatic hernia considered before radiography, all cases being clinically diagnosed as 'acute abdomen', most frequently pancreatitis or perforated peptic ulcer. Even after radiographs had shown opacity at the left base in all 9 cases, together with a distended proximal bowel in 6, the correct diagnosis was made in only 4.

Schistosomal periportal fibrosis produced a typical pattern on computed tomography in five patients. Low-density periportal tissue, present throughout the liver, enhanced strongly after the administration of contrast medium. While rounded in cross section, the thickened periportal tissue produced linear and branching patterns when imaged in longitudinal section.

The hepatic sonograms of 22 patients with the features of schistosomal periportal fibrosis (PPF) were reviewed retrospectively. Dense echogenic bands were seen when scanning along the long axis of the intrahepatic portal vein radicles. Rounded densities resulted from scanning across these bands as they radiated from the porta hepatis to the liver's edge.

Rectocolonic calcification was detected radiographically in 17 sites in 14 patients undergoing excretory urography for the assessment of urinary schistosomiasis. The right colon was involved in 11 sites, the rectum in four, and the left colon in two. The pattern of calcification varied according to the degree of bowel distension.

Four patients who had intravenous pyelography were found to have radiologically visible calcification of the rectocolon and urinary tract due to schistosomiasis. All four patients had mild proctocolitis colonoscopically and multiple calcified schistosomal ova were found in the submucosa histologically. The authors believe that radiologically visible rectocolonic calcification is more common than reported and that it is associated with a clinically mild or latent form of schistosomiasis.

Eleven patients with 12 abdominal abscesses underwent percutaneous insertion of tube drains into the abscess cavities under radiographic control. Once inserted the catheters were managed in the same way as surgically placed drains. Broad-spectrum antibiotic cover was provided.

Synchronous obstruction of large and small bowel may be missed radiologically and even at laparotomy when the small-bowel obstruction masks the large-bowel obstruction. The five patients reported illustrate this problem. It can only be diagnosed in certain patients by barium enema after small-bowel obstruction has been shown on plain radiographs.
