The American literature, until recently, has devoted little space to the subject of congenital cysts of the lung. Koontz,1 in 1925, in an extensive review of the literature, did not find a single paper by an American author describing this congenital anomaly. His bibliography showed that the largest number of cases was reported by the Germans and a few by the English, French and Italians. In the last two years, papers have been published by Miller2 and Moore,3 Americans, and by Smith4 and de Lange,5 foreign authors. The total number of reports occurring in readily accessible literature at the present time amounts to 112.
Briefly reviewing the summary of Koontz' data, one finds that there is no predilection to this condition in either sex. In twenty-six of his 108 cases, the right lung was affected; in forty-six, the left, and in twentyseven cases, both lungs
