Congenital Lung Cyst vs. Bullous Pneumopathy
Left picture: The diagnosis is a congenital lung cyst which partially reaches to the surface and originates from a segment of the left lower lobe. The cyst was removed completely without resection of normal lung tissue. Right picture: In this infant a bullous pneumopathy is the diagnosis, which is a formation of (a) cyst(s) following destruction of lung tissue, and which is supplied by (a) bronchiolus(i) with air. The latter was (were) ligated prior to enucleation or endorhaphy of the cyst(s) as shown in the figure at the bottom.
Left picture: Operative findings in a young infant with increasing respiratory symptoms and signs. Following right-sided thoracotomy a protruding cystic, probably loculated structure is visible between the upper lobe on the left side and the uninvolved segments of the lower lobe on the right side in the picture. Right picture: Operative findings in a newborn with two cystic structures in the left lower lung field, showing a gradually increasing size on radiological follow-up after staphylococcus aureus pneumonia. On the right side a protruding amorphous tissue is visible, and on the left side, adjacent to it, normal lung tissue is recognizable.
