The radiological treatment of hepatic artery aneurysms.
Improvements in the quality and availability of cross-sectional imaging should result in more frequent detection of hepatic artery aneurysms before rupture. Interventional radiological treatment for extra-hepatic lesions has not previously been discussed in the literature. We present two cases of extra-hepatic hepatic artery aneurysms treated using different endovascular techniques and discuss the relative merits of these approaches.

Case report: cellist's elbow?--vascular entrapment in association with the ligament of Struthers.
We present a case of forearm claudication due to ulnar artery entrapment by the ligament of Struthers. Anatomical, radiological and surgical features of this uncommon syndrome are discussed.

Successful treatment by balloon venoplasty and stent insertion of obstruction of the superior vena cava by an endocardial pacemaker lead.
A 63 year old man with symptomatic obstruction of the superior vena cava associated with an indwelling pacemaker was successfully treated with balloon venoplasty and stent insertion. He was symptom free with normal pacemaker function nine months later.

Scrotal ultrasonography: a clinical evaluation.
Two hundred and thirty patients had scrotal ultrasonography over an 18-month period. We report the ultrasound findings, correlation with the clinical diagnosis and, where possible, with the pathological diagnosis. The results show the value of scrotal ultrasonography in clinical practice. Of particular interest is the ultrasonic examination of the clinically normal or impalpable testis and the correct ultrasound diagnosis of testicular tumour in five cases (2% of all cases, 28% of tumours detected) thought clinically to be benign. A brief review of abnormal appearances is included.

Should all casualty radiographs be reviewed?
The effect on the management of patients of routine reporting of casualty radiographs by radiologists was reviewed. The overall prevalence of error by casualty doctors was 6.2%. Many of these errors, however, were trivial and did not alter treatment. In only 1.1% of the cases reviewed did the report of x ray films appreciably alter the management of the patient. A severity score was introduced to highlight those anatomical areas in which important lesions were overlooked most often. Radiologists' reports on radiographs of the chest, face, skull, and wrist had the greatest effect on management of patients, while reports on radiographs of fingers, hands, shoulders, long bones, and toes seldom altered treatment.

A comparison of barium sulphate preparations used for the double contrast barium meal.
Radiologists' opinions of the properties of six barium suspensions with their recommended gas-producing agents designed for upper gastrointestinal use were assessed, using a linear analogue scale. Five radiologists independently assessed mucosal coating of stomach and duodenum, areae gastricae, gaseous distension and bubble formation in a total of 258 patient examinations. Preparation 1 (EZHD) was judged to give best overall results, coating stomach and duodenum particularly well. Preparation 2 (X-Opaque) gave good distension and also coated mucosa fairly well, as did preparations 3 and 4 (Medebar XAC and Field 2C). The latter two preparations produced good distension at the expense of bubble formation. Preparations 5 and 6 (Micropaque DC and Baritop G) were judged, by comparison, to have performed poorly as regards mucosal coating. None of the preparations delineated areae gastricae well, even in the presence of good, bubble-free gastric distension.

The barium enema diagnosis of paracolic abscess.
The barium enema diagnosis of 38 cases of paracolic abscess is discussed. The importance of an appreciation of the anatomy of the peritoneum and of the paracolic region is emphasized. Five features of paracolic abscess that can be recognised on double contrast barium enema examination are analysed. These are soft tissue mass; extraluminal gas collection; barium-filled cavitation; displacement, impression or narrowing of the lumen; and mucosal changes. The commonest feature, present in 95% of cases, is displacement or impression or narrowing of the bowel lumen. An analysis according to site and aetiology is presented and the commonest causes found to be diverticulitis and appendicitis. The differential diagnosis is discussed, and differentiation from primary colonic carcinoma, metastases, Crohn's disease, ischaemia and endometriosis is described.
