Spontaneous regression of a giant pulmonary bulla

Thorax. 1996 May;51(5):549-50. doi: 10.1136/thx.51.5.549.


Gradual expansion of a lung bulla is common and may be associated with debilitating pulmonary symptoms. The aetiology of bulla expansion is unclear. Spontaneous regression, on the other hand, is rarely observed. The case is presented of a man in whom near complete spontaneous resolution of a giant pulmonary bulla occurred. This event was associated with dramatic improvement in the radiographic picture and pulmonary function.
