Invasion of the duodenum by carcinoma of the stomach.

It has frequently been stated that extension to the duodenum occurs commonly in patients with gastric lymphoma but almost never in those with carcinoma of the stomach. We found radiographically detectable invasion of the duodenum in six of 111 consecutive patients (5%) with gastric carcinoma. The duodenum was involved microscopically in 18%. Radiographic abnormalities in the duodenum in 11 patients with proven transpyloric spread of tumor varied from irregularity of the base of the bulb narrowing and distortion extending well into the second portion of the duodenum. On the basis of these data and the reported frequency of transpyloric extension in gastric lymphoma, carcinoma appears to be the more likely diagnosis in a patient with duodenal involvement by an antral tumor.

The variable roentgen appearance of traumatic diaphragmatic hernia.

Alteration of the diaphragmatic contour should be added to the list of radiographic signs of traumatic diaphragmatic hernia (TDH). Such changes may sometimes be appreciated prior to gross herniation of abdominal viscera into the hemithorax. Alterations of the hemidiaphragmatic contour are non-specific, but suggestive of TDH in the appropriate clinical setting.

Stratification in the gallbladder on intravenous cholangiography. The value of delayed or 24-hour radiographs.

Errors in interpretation of intravenous cholangiograms are often made if 24-hour radiographs are not obtained. Three cases are presented in which radiographs, obtained 1/2--4 hours after administration of contrast material, failed to demonstrate gallstones in the visualized gallbladder. However, 24-hour radiographs revealed calculi in all three patients. Stratification of bile is thought to be the mechanism responsible. Delayed radiographs assure proper mixing of contrast material and bile, and provide optimal visualization of the gallbladder in patients undergoing intravenous cholangiography.

Ultrasonographic evaulation of breast masses.

B-mode ultrasonic contact scanning should be performed in conjunction with mammography in any patient with a palpable breast mass that is 1 cm or larger in diameter. Patients with masses that appear cystic on the sonogram should undergo needle aspiration of their masses. The fluid should then be cytologically examined for confirmation of its benign nature and repeat sonograms obtained to ensure that the mass has completely disappeared. Patients with masses appearing either solid or complex ultrasonographically should undergo surgical biopsy.

Computed tomography of blunt trauma to the gallbladder.

The CT findings are reviewed in two patients with injuries to the gallbladder following blunt abdominal trauma. In one patient with a laceration of the cystic artery a large intraluminal clot was identified within the gallbladder associated with extensive hemoperitoneum. Another patient presented with extensive bile leakage into the peritoneal cavity 72 h after blunt trauma due to laceration of the fundus of the gallbladder. The clinical features of blunt trauma to the gallbladder and the utility of CT in this entity are reviewed.
