Differential Diagnosis for Elevated Right Hemidiaphragm

  • Single Most Likely Diagnosis
    • Pulmonary effusion or pleural effusion: This is the most common cause of an elevated hemidiaphragm, as fluid accumulation in the pleural space can push the diaphragm upwards.
  • Other Likely Diagnoses
    • Atelectasis or lung collapse: Collapse of the lung tissue can cause the diaphragm to appear elevated on imaging studies.
    • Pneumonia or lung abscess: Infection and inflammation in the lung can cause the diaphragm to become elevated.
    • Hepatomegaly or liver enlargement: An enlarged liver can push the diaphragm upwards, especially if the liver is significantly enlarged.
    • Subphrenic abscess: An abscess located below the diaphragm can cause it to become elevated.
  • Do Not Miss Diagnoses
    • Diaphragmatic rupture or hernia: A rupture or hernia of the diaphragm can be life-threatening and requires prompt surgical intervention.
    • Pulmonary embolism: A blockage of the pulmonary artery can cause sudden and severe symptoms, including elevation of the hemidiaphragm.
    • Cholecystitis or gallbladder inflammation: Inflammation of the gallbladder can cause referred pain and elevation of the right hemidiaphragm.
  • Rare Diagnoses
    • Diaphragmatic eventration: A rare congenital condition where the diaphragm is abnormal and can become elevated.
    • Diaphragmatic paralysis: Weakness or paralysis of the diaphragm can cause it to become elevated, often due to neurological conditions.
    • Liver or pulmonary tumors: Rarely, tumors in the liver or lung can cause elevation of the hemidiaphragm.
    • Subdiaphragmatic lymphoma: A rare type of cancer that can cause elevation of the hemidiaphragm.
