Our purpose was to describe the CT findings in patients with Bezold's abscesses. ⋯ Bezold's abscesses are rare complications of mastoiditis. In our series most were seen in adults and were associated with a history of cholesteatoma and mastoidectomy. CT of the neck and temporal bone can help the surgeon determine appropriate treatment.

Anatomy of the normal brachial plexus revealed by sonography and the role of sonographic guidance in anesthesia of the brachial plexus.
The purpose of this study is to describe the sonographic appearance of the normal brachial plexus and to evaluate the use of imaging guidance for brachial plexus anesthesia. ⋯ High-resolution sonography can show normal brachial plexus anatomy and facilitate catheter-based brachial plexus anesthesia without complications.

Nonspecific interstitial pneumonia with fibrosis: high-resolution CT and pathologic findings.
The purpose of our study was to describe high-resolution CT findings of nonspecific interstitial pneumonia with fibrosis and to compare findings seen on CT with pathologic findings. ⋯ On high-resolution CT, nonspecific interstitial pneumonia with fibrosis is most commonly revealed as patchy subpleural areas of ground-glass opacity mixed with irregular linear opacity or bronchial dilatation. These areas represent interstitial thickening caused by varying degrees of interstitial inflammation, fibrosis, or both.

Validity of CT classification on management of occult pneumothorax: a prospective study.
In the setting of blunt trauma, abdominal CT, which routinely includes images of the lower thorax, frequently reveals pneumothoraces that have not been detected on routine supine chest radiographs. Proper management of these occult pneumothoraces remains controversial. The purpose of this study was to test the hypothesis that small (minuscule) to moderate (anterior) radiographically occult pneumothoraces can be safely managed without chest tube placement for patients in whom the need for positive pressure ventilation is not anticipated. ⋯ Most small (minuscule) occult pneumothoraces can successfully be managed with close observation. The risk that the pneumothorax will progress is slight. Moderate-sized (anterior) pneumothoraces may also be successfully managed without initial placement of a chest tube if the patient is not to undergo positive pressure ventilation.

Sonographic guidance when using the right internal jugular vein for central vein access.
The intent of this study was to substantiate the advantages of the use of sonographic guidance for central venous access via the right internal jugular vein. ⋯ Sonographic guidance for central vein access via the right internal jugular vein is safer and more efficient than the traditional landmark approach.
