Complicated pneumothorax and congenital lung cystic malformation.

Abstract

Congenital cystic adenomatoid malformation, also named congenital pulmonary airway malformation (CPAM), is a congenital lung abnormality which is uncommon in adults. The usual radiological appearance of CPAM is a cystic space-occupying lesion. We present one case of CPAM with unusual clinical and radiological findings, a complicated spontaneous pneumothorax with intracystic haemorrhage with successful conservative initial treatment, despite acute haemodynamic instability.
