A comparative assessment of tube esophagography with double-contrast esophagography in the detection of reflux esophagitis.
We undertook a prospective study comparing the sensitivities of double-contrast and tube esophagography in 34 patients with gastroesophageal reflux and compared our findings with those at endoscopy. Neither test detected changes accurately in mild inflammation; however, they both became more sensitive as the severity of esophagitis increased. The sensitivity of both tests increased from 0% in grade 2 to 86% in grade 4 esophagitis. The tube esophagogram demonstrated inflammatory changes better than the double-contrast esophagogram in only 18% of the 34 patients, all with grade 3 or 4 esophagitis, despite the elimination of the barium pool in the distal esophagus and improved distension of the esophagogastric junction. Endoscopy is still the most reliable means of diagnosing and grading esophagitis.

Sonographic diagnosis of leiomyosarcoma of the inferior vena cava: correlation with computed tomography and angiography.
We describe a patient with leiomyosarcoma of the inferior vena cava. There has been no previous report of the sonographic diagnosis of this rare entity.

Placental chorioangioma, an unusual cause of polyhydramnios: antenatal diagnosis.
I report a patient with placental chorioangioma producing third trimester polyhydramnios. The ultrasonographic diagnosis and the complications of this tumor are discussed.

Segmental renal venous catheterization: technical note.
I describe a technique for superselective catheterization of the renal segmental veins which does not require specialized equipment.

Recurrent hepatoma with CT, MRI, and angiographic correlation.
Two patients who underwent successful resections for uninodular hepatomas in non-cirrhotic livers were readmitted with late recurrences. Both had multiple imaging procedures prior to treatment including computed tomography, magnetic resonance imaging, and angiography. I recommend periodic ultrasonography and alphafetoprotein assay in the follow-up of patients who have had a hepatoma resected and I indicate when additional imaging methods are required.

Reliability of amniotic fluid volume estimation from ultrasonograms: intraobserver and interobserver variation before and after the establishment of criteria.
This study assesses levels of intraobserver and interobserver agreement for the determination of decreased and normal amniotic fluid volumes, both before and after the development of criteria. Good to excellent levels of agreement were obtained. Agreement may be higher after the development of criteria and may be higher for more experienced ultrasonographers.

NSAID injury to the small intestine.
PURPOSE: To identify the clinical and radiologic findings in patients with diaphragm-like strictures in the small bowel. PATIENTS AND METHODS: We reviewed the histories, radiologic findings, and pathologic findings in two men and two women, all in their sixties, with a history of long-term nonsteroidal antiinflammatory drug (NSAID) or aspirin (ASA) usage and one or more radiologically demonstrated diaphragm-like strictures in the small bowel. RESULTS: Two patients had long histories of NSAID usage, and two of ASA usage. One NSAID user had a long segment of jejunal involvement, and the other three had short segments of duodenal involvement. The ASA users presented with symptoms of esophageal disease, the small bowel lesions were unexpected, and ASA usage was not initially elicited. In one NSAID user and one ASA user, broader strictures with humps rather than diaphragms were also seen producing a lifesaver-like or bagel-like configuration. CONCLUSIONS: Multiple diaphragm-like strictures can occur in NSAID injury and are pathognomonic except in the rare patient with ulcerative enteritis complicating celiac disease. Single or few diaphragm-like strictures can occur in NSAID injury and peptic ulceration. ASA should be considered an NSAID with regard to small-bowel toxicity. A careful medication history is required when an unexplained small bowel abnormality is seen radiologically, and a dedicated small bowel examination is required when NSAID injury is suspected.

Recurrent Crohn's disease in the duodenum and jejunum following extensive small bowel resection and jejunocolonic anastamosis: radiologic findings in twenty-five patients.
BACKGROUND: To evaluate the radiologic features of recurrent Crohn's disease after extensive enteric resection and jejunocolostomy. METHODS: We reviewed the small bowel studies of 25 patients with recurrent enteritis and less than 125 cm of jejunum following enteric resection and jejunocolostomy and the studies of 27 patients with jejunitis in an intact jejunum. RESULTS: Twenty-three patients with recurrences had neoterminal jejunitis, six under 10 cm, 10 over 10 cm and continuous, and seven with skip lesions (six jejunal, one duodenal). Two had isolated jejunitis or duodenitis. Three with continuous disease had lengthy recurrences. Enteritis showed only one or two abnormalities in 12 of 25 patients with recurrences and in two of 27 with disease in the intact jejunum. Recurrent jejunitis and jejunitis in the intact jejunum showed similar frequencies of mucosal thickening, strictures, ulceration and its complications, skip lesions, sacculation, obstructive dilatation, featureless mucosa, and polyps, and significantly different frequencies only of mesenteric masses. Recurrent jejunitis and terminal ileitis showed significantly different frequencies of mucosal thickening, strictures, ulceration and its complications, skip lesions, sacculation, obstructive dilatation, and mesenteric masses, and similar frequencies only of a featureless mucosa. CONCLUSIONS: The neoterminal jejunum is the most common site of recurrence and the only site in almost 25%. Jejunitis remote from the fecal stream is also frequent, but duodenitis is not. Recurrences are seldom extensive and often show only one or two radiographic findings. The frequencies of most lesions in recurrent jejunitis do not differ significantly from those in jejunitis in the intact jejunum but do differ from those in terminal ileitis.

Venous intravasation of barium: CT findings.
Portal venous barium and air intravasation occurred during an air contrast enema in a man with ulcerative colitis. Abdominal plain radiography and CT subsequently showed increased hepatic density. Computed tomography also showed colonic intramural and pericolic nodal or venous barium, increased splenic density, and pulmonary arterial barium. The patient's course was benign because little barium embolized beyond the liver into the systemic circulation.

Pancreaticoduodenal tuberculosis simulating metastatic ovarian carcinoma.
A patient from Thailand presented with symptoms suggestive of peptic ulceration. Radiology showed an ulcerated duodenal stricture, a pancreaticoduodenal mass and extensive retroperitoneal lymphadenopathy suggestive of metastatic carcinoma. Tuberculosis was diagnosed only at laparotomy. The incidence of tuberculosis is increasing, and alimentary tuberculosis should be considered in patients from populations at risk presenting with obscure abdominal complaints or unexplained radiologic findings.
