Colitis cystica profunda.

A 39-year-old woman with inflammatory bowel disease was admitted to the hospital because of cramping abdominal pain and diarrhea. Ultrasound of the abdomen revealed thickening of the wall of the descending colon. At endoscopy mucosa-covered nodules with substenosis were seen.

Ectopic gastric mucosa presenting as a polypoid mass within a Meckel's diverticulum.

A 32-year-old man presented with severe abdominal pain located in the mesogastrium and right hemi-abdomen. A barium transit study showed a tubular structure of 6 cm arising from a bowel loop in the distal ileum, with an intraluminal polypoid mass near the bottom. Diagnosis of a benign lesion within a Meckel's diverticulum was made.

Pelvic floor descent in females: comparative study of colpocystodefecography and dynamic fast MR imaging.

The purpose of this study was to compare fast dynamic magnetic resonance imaging (MRI) with colpocystodefecography (CCD) in the evaluation of pelvic floor descent in women. Thirty-five women with clinical evidence of pelvic floor descent were studied. A fast single-shot MR sequence was performed in the supine position during pelvic floor relaxation and during maximal pelvic strain.

Radiologic investigations and pathologic results of experimental chronic pancreatitis in cats.

Rationale And Objectives: The purpose of this study was to evaluate a variety of methods to induce chronic pancreatitis and its radiologic expression by experimentally inducing this condition in cats.

Materials And Methods: Chronic inflammatory and fibrosing pancreatitis was produced in cats by intraductal injection of 1.5 mL of 94% ethanol in one group or by a combination of intraductal and intraparenchymal injection of ethanol together with partial obstruction of the main pancreatic duct to 70% of its original lumen by fixation of a small catheter in the papilla.

Ischemic jejunitis caused by primary small bowel volvulus.

A case of ischemic jejunitis caused by primary small bowel volvulus is presented. The radiological signs of ischemia persisted after detorsion. Contrast examinations of the small intestine demonstrated severe jejunitis with ulcerations, segmental narrowing and fistulas.

Healing of severe recurrent ileitis with azathioprine therapy in patients with Crohn's disease.

Background & Aims: Standard corticosteroid therapy for Crohn's ileitis induces symptom relief without improvement of endoscopically visible lesions. In this study, the effect of azathioprine therapy on the inflammatory lesions in the neoterminal ileum of patients with severe postoperative Crohn's recurrence was examined.

Methods: Macroscopic ileal lesions were studied endoscopically or radiologically after at least 6 months of azathioprine therapy after complete weaning of corticosteroids.

Mechanisms involved in postdeglutition retention in the elderly.

This study examines possible quantifiable causes of postdeglutition pharyngeal retention in the elderly. Manofluorography and computer processing of video images are performed. Retention in the valleculae and in the piriform sinuses is associated with a markedly reduced pharyngeal shortening, a low tongue driving force (TDF), and a diminished amplitude of the pharyngeal contraction.

Imaging of gallbladder and biliary tract before laparoscopic cholecystectomy: comparison of intravenous cholangiography and the combined use of HASTE and single-shot RARE MR imaging.

To compare intravenous cholangiography (i.v.c.

Esophageal tuberculosis mimicking malignancy.

A case of pulmonary and esophageal tuberculosis in an 82-year-old female is presented. Esophageal tuberculosis is very rarely seen in Europe and the United States, but the disease is still endemic in India. The major differential diagnosis is esophageal malignancy.

The evolution of radioprotection.

In comparison with the first half of this century the frequency of X-ray induced lesions diminished spectacularly both in patients and in radiologists in the second half; this was due to more and more rigorous radioprotection. The present measures of radioprotection may be divided into two groups according to their appliance to the patient or the operator. Prevention of irradiation of an unknown pregnancy is the responsibility of the clinician (application of the 10 days rule) but equally of the radiologist (warning poster in the radiological department, query of possible pregnancy).

[The history of gallbladder and bile duct diagnosis].

In the first period (1896-1910), investigation was made through plain abdominal film with description and differential diagnosis of the different calcifications in the right hypochondrium. Second period (1911-1924): indirect signs of liver and gallbladder pathology were described. Via pneumoperitoneum and gastro-intestinal opacification the pathology in the right hypochondrium was delineated and interpreted.

Intermittent subobstruction and cholestasis as complications of duodenal amyloid tumours.

Amyloidosis confined to the duodenum is uncommon. In the present report the history of an 83-year old patient, admitted for vomiting and heavy epigastric pain, is described. Radiographic and endoscopic investigation revealed two polypoid lesions in the duodenum (D2).

Esophageal metastasis from breast carcinoma.

A case of esophageal metastasis from a breast carcinoma is presented. Location was, as usual, midesophageal. The interval of time between breast carcinoma and the onset of esophageal symptoms was rather long.

Three cases of non-tumoural tight stenosis of the bifurcation of the hilar bile ducts.

Stenosis of the bifurcation of the hepatic bile duct is usually caused by malignant lesion. We report on three different causes of benign stenosis of the hepatic confluence with a similar radiological pattern on direct cholangiography. The first case is considered a spontaneous neuroma, the second a periductal abscess, and the third case a postoperative stricture Bismuth type 4.

CT findings in nonmucosal eosinophilic gastroenteritis.

A 22-year-old patient with eosinophilic gastroenteritis with predominantly submucosal and muscular involvement is presented. The benefits of CT, using water as an orally administered contrast agent, are stressed, because CT enabled the authors to suggest a full thickness biopsy, after mucosal biopsies had remained repeatedly negative.

Sonographic diagnosis of ischemic colitis.

An abdominal ultrasound examination performed on two patients with abdominal pain showed segmental wall thickening of the colon that proved to be due to ischemic colitis. In one case, the typical "target lesion" was recognized. These findings could be confirmed with computed tomography, whereas a single contrast enema was unable to demonstrate the ischemic disease.

Gastric volvulus as a complication of a left superior lobectomy in a patient with pre-existing hiatal hernia.

The case of a 75-year-old man with a history of hiatal hernia, who develops an acute gastric volvulus 17 days after a superior lobectomy of the left lung, is described. No similar cases were found in literature.

Imaging of polypoid endoluminal growing bile duct tumors.

We reviewed the radiological documents and protocols of 196 cases of bile duct tumors examined over a period of 12 years: 20 of them (10.2%) presented with a polypoid endoluminal growth. The aim of this study was to provide a better knowledge about the radiological features of this less frequent kind of tumor.

Effect of body position on deglutition.

This study examined the effects of changes in body position on different swallowing parameters derived from manofluorographic examinations. Quantitative data were obtained in a group of 12 young healthy volunteers. They were all tested in the upright position; six of them were also evaluated in the supine position, and the other six in the upside down position.

Manofluorographic analysis of swallowing in the elderly.

This study examined the effect of aging on the mechanisms of swallowing by comparing 16 elderly subjects (80 years +/- 5) with 20 healthy volunteers. Manofluorography was used to obtain quantitative and qualitative data of the pharyngeal swallow. Aging is associated with a significant decrease in the level of negative pressure resulting from the opening of the upper esophageal sphincter and with a substantial number of incomplete relaxations of the sphincter.

Proctitis and rectal stenosis induced by nonsteroidal antiinflammatory suppositories.

Anorectal ulceration eventually leading to rectal stenosis was observed in 10 patients who abused analgetic suppositories containing acetylsalicylic acid, acetaminophen, and codeine. Most patients were middle-aged women with a neurotic or psychiatric background. Perianal skin lesions were present in half of the patients.
