Rheumatoid arthritis: skeletal manifestations observed on portable chest roentgenograms.

This report describes the thoracic skeletal radiographic findings of rheumatoid arthritis, observed on portable chest examinations of 21 patients. Their pathophysiology is reviewed and additional examples of a recently described finding are illustrated: erosion of the medial surface of the proximal humerus with subsequent pathologic fracture, associated with superior and medial migration of the humeral head. It has been proposed that erosion of the medial aspect of the proximal humerus is due to impingement wear, and that pathologic fracture results from the fulcrum effect of the inferior lip of the glenoid on the humerus. Rheumatoid arthritis is often diagnosed by the clinician rather than the radiologist. However, in acutely ill patients receiving portable chest radiographs, complete history and laboratory findings are often unavailable. Attention to the thoracic skeleton may clarify pleural and/or parenchymal lung disease in these patients.

Bronchiectasis in childhood. Comparison of chest roentgenograms, bronchography and lung scintigraphy.

In 76 children, 102 unilateral bronchograms were compared with the results of chest radiography and Tc-99m perfusion scintigraphy to assess the presence of bronchiectasis. Additional Kr-81m ventilation lung scintigraphy was obtained in 16 patients. For the chest radiograph the sensitivity was 73% and the specificity was 76%. For lung scintigraphy the sensitivity was 92% and the specificity 60%. When both chest radiography and lung scintigraphy were considered, sensitivity reached 96% and specificity fell to 53%. Forty per cent of the bronchrograms which were performed might have been avoided on the basis of the normal chest radiograph and lung scintigraphy. The combination of lung scintigraphy and chest radiography is an excellent screening method when a decision on the advisability of bronchography is being taken in children.
