An air bronchogram, fluid bronchogram, and scattered echogenic foci due to residual air in the consolidated lung parenchyma were used as US criteria of pulmonary parenchymal consolidation. One or more of these signs were observed in 39 patients with a clinical or bacteriologic diagnosis of pneumonia. The US air bronchogram was seen in 32 of the 39 patients (82 %), the fluid bronchogram in 37 patients (94%) and the scattered echogenic foci in 30 (77%). In 14 patients, pleural effusion was diagnosed sonographically and verified by aspiration of fluid. The final diagnoses in these cases were pulmonary tuberculosis in 11 patients, staphylococcal empyema in 2, and tuberculous empyema in one patient. It is concluded that US criteria provide a useful differentiation of pulmonary parenchymal consolidation from pleural effusion.

Material and Methods: Flamingo stents were placed under fluoroscopic guidance between August 1998 and December 1999 for palliation of malignant dysphagia in 33 cases. There were 21 males and 12 females aged 40–80 years (average 64.2 years). Results: Stent placement was successful in all patients, with good symptomatic control and no procedure-related complications. Spontaneous esophago-respiratory fistula and perforation accompanying malignant esophageal stricture in a total of 4 cases (12.2%) were successfully closed. In 1 case, tumor ingrowth was detected from the distal uncovered segment of the stent. In 2 cases with esophago-respiratory fistula, gastrointestinal bleeding occurred. The cause of hemorrhage could not be found by angiography. The mean survival time in 17 patients, later deceased, was 129 days (range 9–360), and the mean observation time in 16 patients still alive is 180 days (range 18–365). Conclusion: Flamingo stents provide an effective and safe choice of palliative therapy in inoperable malignant esophagogastric strictures.
Rupture of a metastatic liver tumor associated with laryngeal cancer is a very rare complication ... more Rupture of a metastatic liver tumor associated with laryngeal cancer is a very rare complication with no previous case in the literature. We present a case of ruptured liver metastases which was treated conservatively. Dynamic contrast-enhanced computed tomography demonstrated active extravasation and discontinuity of liver capsule. When the patient came to our hospital from the external medical center, we did not see active extravasation on control computed tomography. This case highlights the role of radiologic imaging in the diagnosis and follow-up of ruptured hepatic metastases.

In all thalassemias clinical features that result from anemia, transfusional, and absorptive iron overload are simi- lar but vary in severity. The radiographic features of b-thalassemia are due in large part to marrow hyper- plasia. Markedly expanded marrow space lead to var- ious skeletal manifestations including spine, skull, fa- cial bones, and ribs. Extramedullary hematopoiesis (ExmH), hemosiderosis, and cholelithiasis are among the non-skeletal manifestations of thalassemia. The skeletal X-ray findings show characteristics of chron- ic overactivity of the marrow. In this article both skel- etal and non-skeletal manifestations of thalassemia are discussed with an overview of X-ray findings, in- cluding MRI and CT findings.

The urethral strictures were successfully negotiated and dilated in all patients. Redilatation became necessary in a period ranging from 3 to 10 months. The authors believe that balloon dilatation of the urethra can be safely and successfully performed; the procedure produces minimal trauma and immediate relief of symptoms.

Here we report a 13-year-old female patient presenting with generalized lymphadenopathy, who meanwhile developed butterflly rash and pericarditis. The diagnosis of SLE was based on the clinical features, positive antinuclear antibody, and positive antibodies to dsDNA. The patient had an active disease and developed renal involvement, despite steroid therapy. The patient's clinical presentation, course and response to therapy are detailed, and the literature on lupus lymphadenitis is reviewed.

In this report, we present endovascular stent grafting for symptomatic treatment of severe thoracic aortic stenosis caused by an aortic sarcomatoid carcinoma in a 73-year-old female. The peri- and post-operative courses were complicated with tumor embolisms that were managed by both endovascular and surgical measures.

The aim of this study was to determine whether the oral administration of a polyethylene glycol (PEG)-electrolyte solution induces adequate luminal distention for magnetic resonance (MR) colonography to be performed and to assess patient acceptance of this procedure. Fifty-five patients (26 women, 29 men; mean age, 60.5 years +/- 14 [standard deviation]; age range, 40-75 years) who were referred for optical colonoscopy (OC) owing to symptoms and findings that included rectal bleeding, altered bowel habits, and positive fecal occult blood test results participated in this study. Standard bowel preparation was performed 1 day before the procedure. MR colonography was performed and followed by OC on the same day. Before undergoing MR colonography, the patients received 2.0-2.5 L of the PEG-electrolyte solution orally. Adequate distention of all colonic segments was achieved in 50-53 (91%-96%) of patients imaged in the supine position and in 51-53 (93%-96%) of patients imaged in the prone position. Oral administration of the solution yielded uniform luminal darkening and sufficient colonic distention for MR colonography in 91%-96% of patients.
