Case ReportsElliptical cricoid cartilage: a unique type of congenital subglottic stenosis.

An "hourglass" deformity of the subglottic laryngeal airway on an anteroposterior airway radiograph is suggestive of this diagnosis.

Case ReportsNeonatal aortoiliac compression caused by a distended bladder.

Real-time sonography can permit recognition of the abnormality, demonstration of the related pathophysiology, and exclusion of other causes of aortoiliac occlusion.
