What causes hemidiaphragm paralysis. Surgical flattening of the dome-shaped diaphragm to allow lung expansion technically known as diaphragmatic plication. Elevated hemidiaphragm occurs when one side of the diaphragm becomes weak from muscular disease or loss of innervation due to phrenic nerve injury. A high hemidiaphragm implies reduced lung volume which can result from phrenic nerve paralysis thoracic conditions causing chest pain that leads to splinting or extrapulmonic processes such as an enlarged spleen or liver pancreatitis or subphrenic abscess.

The causes and risk factors that compromise diaphragmatic function include. Direct trauma to the phrenic nerve the nerve that controls the function of the diaphragm either from surgery radiation or tumor Central neurological disorders such as a brain or brainstem stroke.

Cancer in the lung or in the lymph nodes which can grow into or compress the nerve. The motor supply of each hemidiaphragm comes purely from the phrenic nerves and so conditions affecting the phrenic nerve or its nerve roots cause hemidiaphragm paralysis. Unilateral diaphragmatic paralysis is a condition caused when one side of the diaphragm becomes weak or paralyzed.

You may not have heard about phrenic nerve. In patients where one side of the diaphragm is paralyzed people usually have no symptoms unless they have another reason for shortness of breath asthma emphysema etc. The phrenic nerves C345 supply motor function to the hemidiaphragms.

Diaphragmatic paralysis also considered very similar to the term diaphragmatic palsy can be unilateral or bilateral. Patients may present with difficulty breathing but more commonly elevated hemidiaphragm is found on imaging as an incidental finding and patients are asymptomatic. It means patient does not experience any.
