A bullae can only be detected by a radiological method. A doctor will be able to perform an x-ray or a CAT scan to decide if a bullae is present. These tests will be ordered when a person has any symptoms of a bullae. People who have soreness of the chest, difficulty breathing in, overall fatigue and a bloated feeling may have a bullae on one of their lungs. These bullae often do not occur on their own and are the result of illness or injury in the area of the lung.

When a bullae is present and ruptures, it can cause a condition known as pneumothorax. This condition can be fatal and can lead to the function of the lungs being decreased. This condition can cause the lung to have a persistent air leak, can cause shock and can also lead to cardiac arrest. People who have experienced bullae should be closely monitored by their doctors to ensure they are not experiencing pneumothorax.
