@entity600 are uncommon but potentially life-threatening anomalies of @entity1 and @entity1 . Between 1970 and 1988, 45 @entity1 from birth to 13 years of age (23 @entity1 and 22 @entity1 ) underwent evaluation and treatment for @entity600 . Thirty-seven had solitary lesions: bronchogenic cyst (n = 13), @entity2977 (n = 9), @entity14943 (n = 6), @entity18697 (n = 6), @entity2758 (n = 2), and @entity2488 (n = 1). Eight additional @entity1 had two simultaneous abnormalities and three @entity1 had @entity2914 . Twenty-one @entity1 had respiratory symptoms, which were severe in seven. Twelve had @entity358 and 10 @entity1 were completely free of symptoms. Plain chest roentgenogram was the only diagnostic imaging performed in 11 @entity1 . Thirteen @entity1 underwent computed tomographic scan, but in only four was it essential for diagnosis. Prenatal ultrasonography in three @entity1 demonstrated @entity2977 in two, with one false negative study. Postnatally, ultrasonography was also useful in establishing the diagnoses of @entity2977 and @entity18697 . Thoracotomy with excision of the lesion by lobectomy or pneumonectomy resulted in survival of 42 @entity1 (93%). Three deaths in neonates were due to @entity358 and @entity101 . Two of them had concomitant @entity2914 ; the other had a @entity2977 and died despite the use of postoperative extracorporeal membrane oxygenation. These data demonstrate that @entity600 usually can be diagnosed by plain chest x-ray films. Ancillary studies such as ultrasonography or computed tomography may occasionally be necessary. Combinations of the different types of @entity600 occurred frequently. All lesions, including symptomatic lesions in neonates, can be managed surgically soon after diagnosis.
