RESUMEN
Internal jugular thrombophlebitis usually results from contiguous infection or central catheterization. Ultrasonography and CT allow rapid, noninvasive methods of confirming the diagnosis of this condition. Although the choice of modality has not been systematically examined, where local expertise exists for both, ultrasonography is less expensive and should provide adequate images.

We reviewed our experience with computerized tomography (CT) of the abdomen in 212 patients with histologically documented liver neoplasms seen during a 30-month period. The CT findings in cavernous hemangioma and focal nodular hyperplasia were specific, and permitted accurate diagnosis of this lesion before biopsy. The CT appearance of all other lesions was variable. We consider CT useful in providing an accurate evaluation of the intrahepatic and extrahepatic extent of the neoplasm.

Ten cases of sclerosing cholangitis, both primary and secondary forms, were found to have similar abnormalities within the liver on CT examinations. These changes are different from those seen in cases of biliary obstruction due to tumor, stone, inflammatory mass, or other focal process. The finding of focal, discontinuous areas of minimal intrahepatic biliary dilatation without associated mass lesion seems to be highly suggestive of sclerosing cholangitis. Only the rare, diffuse form of cholangiocarcinoma would be likely to produce a similar CT appearance.

The use of vasopressin infusion or arterial embolization in the treatment of 87 patients with gastrointestinal hemorrhage is reviewed. A bleeding point was identified angiographically in 46 patients (53%), with a higher success rate in those with upper gastrointestinal hemorrhage (63%) than in those with lower (39%) gastrointestinal hemorrhage. Vasopressin infusion in 33 patients completely stopped hemorrhage in 14 and slowed hemorrhage pending surgery in another 5. Gelfoam embolization was successful as definitive therapy in 12 of 15 patients. Mortality as a result of hemorrhage or its sequelae was 40% in patients with upper gastrointestinal hemorrhage and 21% in those with lower gastrointestinal hemorrhage.

We have described a 24-year-old diabetic woman with rapidly developing left-sided tension hydrothorax. The pleural effusion was characterized by high contents of protein and glucose. The chest roentgenogram exhibited massive pleural effusion, prominent air bronchograms, mediastinal shift, and diaphragmatic inversion. Prompt thoracocentesis proved to be life-saving.
