What Is an Elevated Hemidiaphragm?

Q:
What is an elevated hemidiaphragm?

A:
When we breathe, the diaphragm would separate the chest cavity from abdomen by rising and falling. When half of a patient’s diaphragm appears to be raised or elevated, it is called elevated hemidiaphragm.

Elevated hemidiaphragms can result from many causes:

  • Above the diaphragm: in the chest there may be a decreased lung volume that is caused by lobectomy/pneumonectomy or pulmonary hypoplasia.
  • In the diaphragm: The hemidiaphragm may be paralyzed or lax because of phrenic nerve palsy or diaphragmatic eventration.
  • Below the diaphragm: there may be a subphrenic abscess, an infection in the abdomen or an abdominal tumor, e.g. liver metastases or primary malignancy.
  • Abdominal surgery and pancreatitis sometime also cause Temporary elevation of a hemidiaphragm.

Generally, an elevated hemidiaphragm does not definitely indicate some acute diseases, but it’s a clue of some health problems.

In any case though, if you or someone close to you feels as if they have an underlying issue going on, please go see a doctor for professional help.
