Chest roentgenography as a window to the diagnosis of Takayasu's arteritis.
The chest roentgenographic findings in Takayasu's arteritis include widening of the ascending aorta, contour irregularities of the descending aorta, arotic calcifications, pulmonary arterial changes, rib notching, and hilar lymphadenopathy. The single most important diagnostic sign is a segmental calcification outlining a localized or diffuse narrowing of the aorta. The other signs may be suspicious or suggestive, but the diagnostic accuracy increases when several findings are present simultaneously.

Hypoxia, pulmonary edema, acidosis, and aspiration compose the syndrome of near drowning. A review of 20 cases of near drowning indicated that the initial chest roentgenogram bears little weight in assessing the present or future clinical status. ⋯ The composition of fluid aspirated does not affect the outcome. The results of this report suggest that patients with a history of near drowning should be followed closely for at least 48 hours despite an initial normal chest roentgenogram.
