Children with PPB may experience the following symptoms or signs. Sometimes, children with PPB do not show any of these symptoms. Or, these symptoms may be caused by a medical condition that is not a tumor. Because PPB is so rare, doctors often believe at first that the symptoms are caused by a common childhood illness.
There are two common sets of symptoms that may indicate PPB:
- Sudden, stressful breathing may be caused by air escaping from the lung cysts into the chest cavity. This is called pneumothorax, meaning there is air in the chest cavity. However, there are many other causes of pneumothorax.
- Symptoms of PPB may be exactly the same as symptoms of pneumonia, a lung/respiratory infection. These symptoms may include generally feeling unwell, cough, fever, and pain in the chest. Even when a chest x-ray is done, it may be first interpreted as pneumonia. It is common for children with PPB to have been treated for two to three weeks for pneumonia before more tests show that they do not have an infection, but likely have a tumor in the chest.
In addition, sometimes a lung cyst or tumor may be found when a chest x-ray is taken for another reason. See the Diagnosis  section for more information on chest x-rays.
If you are concerned about one or more of the symptoms or signs on this list, please talk with your child’s doctor. Your doctor will ask how long and how often your child has been experiencing the symptom(s), in addition to other questions. This is to help find out the cause of the problem, called a diagnosis .
If a tumor is diagnosed, relieving symptoms remains an important part of your child’s medical care and treatment. This may also be called symptom management, palliative care, or supportive care. Be sure to talk with the health care team about symptoms your child experiences, including any new symptoms or a change in symptoms.
The next section helps explain what tests and scans may be needed to learn more about the cause of the symptoms. Use the menu on the side of your screen to select Diagnosis, or you can select another section, to continue reading this guide.
