ABSTRACT
Superior vena cava aneurysms are rare mediastinal vascular lesions. Aneurysms are classified as fusiform and saccular, with the latter being rarer than the former. We report the case of an asymptomatic 75-year-old woman who presented with a superior mediastinal mass. She underwent chest computed tomography angiography, which demonstrated a saccular aneurysm in the superior vena cava.

OBJECTIVE: The purpose of this study was to evaluate pulmonary manifestations of ankylosing spondylitis on inspiratory and expiratory high resolution CT. MATERIAL AND METHODS: The study included 17 patients ranging from 40 to 62 years in age. Fifteen patients were male, and 8 were smokers. All patients underwent chest radiography and high-resolution CT. High-resolution CT was obtained using 1 or 2 mm collimation scans at 10-mm intervals at the end of maximal inspiration and at 3 cm intervals at the end of maximal expiration. RESULTS: Pulmonary abnormalities were evident on chest radiography in 2 patients and on CT in 15 patients. The abnormalities on CT included evidence of airway disease in 14 (82%), interstitial abnormalities in 11 (65%), and emphysema in 6 (35%) patients. Airway abnormalities included bronchial wall thickening in 7 (41%), mosaic perfusion in 3 (18%), centrilobular nodules in 3, bronchiolectasis in 2, and air trapping on expiratory CT in 7 (41%) patients. Interstitial abnormalities included parenchymal bands in 7 (41%), intralobular linear opacities (n = 2), and 1 patient each with irregular thickening of interlobular septa, subpleural lines, and honeycombing. CONCLUSION: The majority of patients with ankylosing spondylitis have airway and interstitial abnormalities evident on high-resolution CT. These abnormalities are usually mild and therefore seldom evident on the chest radiograph.
