Case ReportsInfra-azygous pneumomediastinum versus pulmonary ligament air collection: CT evaluation.
A full-term infant developed a large collection of air posteriorly in the thorax. Computed tomography showed the anatomical distribution of this extraventilatory air and although, it did not conclusively differentiate between infra-azygous pneumomediastinum and a pulmonary ligament air collection, inappropriate needle aspiration of the air was avoided.

Comparative StudyA comparison of the Shwachman, Chrispin-Norman and Brasfield methods for scoring of chest radiographs of patients with cystic fibrosis.
Three systems are described for chest radiograph scoring in cystic fibrosis patients: the Shwachman-Kulczycki, the Chrispin-Norman and the Brasfield method. Sixty chest radiographs of 39 patients of different ages have been independently scored by two radiologists according to the three methods. ⋯ The Chrispin-Norman method is recommended as the best choice because differences in scoring appeared better interpretable. A significant increase in precision could be achieved by combining the scores of the three methods.

A baby with two lower cervical tracheoesophageal fistulas was evaluated with a barium esophagram and computerized tomography (CT). The esophagram identified both fistulas. Axial CT demonstrated the esophageal attachment of the upper fistula and completely displayed the lower fistula. A change in caliber of the esophagus from a collapsed to a distended state marked the site of the fistulas.
