Spontaneous pneumothorax in allergic bronchopulmonary aspergillosis.

A new roentgenographic finding of spontaneous pneumothorax occurred in a patient with well-advanced (stage V) allergic bronchopulmonary aspergillosis (ABPA). The pneumothorax responded to chest tube evacuation. Patients with well-advanced ABPA and severe chest pain should be carefully examined and treated for pneumothorax, to maintain as much functioning lung as possible.
