RESUMO
An elderly man presented with progressive atelectasis of the left lung, a mediastinal mass, and dilatation of the thoracic aorta. Ventilation and perfusion radionuclide lung scans revealed the complete absence of ventilation in the left lung and near-complete absence of perfusion. Evaluation by MRI and angiography showed an obstructing mediastinal "mass" to be a saccular aortic aneurysm. A thoracic aortic aneurysm should be a consideration in the differential diagnosis for unilateral decrease or absence of ventilation and perfusion with a history or findings of mediastinal mass or aneurysm.

Dialysate leakage into subcutaneous tissues occurs not uncommonly in patients on continuous ambulatory peritoneal dialysis. When the leakage site cannot be localized clinically, CT with intraperitoneal contrast medium administration may localize the site. We report our experience with three cases in which this technique did localize the leakage site and thereby determined the type of surgical correction.
