Differential Diagnosis for Congestive Heart Failure with Ascites but no Liver Enlargement

Single Most Likely Diagnosis

  • Congestive Heart Failure (CHF) due to Left Ventricular Dysfunction: This is the most likely diagnosis, as CHF can cause fluid accumulation in the body, leading to ascites. The absence of liver enlargement suggests that the liver is not significantly affected, which is consistent with left ventricular dysfunction as the primary cause.

Other Likely Diagnoses

  • Constrictive Pericarditis: This condition can cause CHF symptoms, including ascites, without significant liver enlargement. The pericardial constriction can impede the heart's ability to fill, leading to fluid accumulation.
  • Restrictive Cardiomyopathy: Similar to constrictive pericarditis, restrictive cardiomyopathy can cause CHF symptoms, including ascites, due to the heart's inability to fill properly.
  • Tricuspid Regurgitation: Severe tricuspid regurgitation can cause right-sided heart failure, leading to ascites without significant liver enlargement.

Do Not Miss Diagnoses

  • Cardiac Tamponade: Although less likely, cardiac tamponade is a life-threatening condition that can cause CHF symptoms, including ascites. It is essential to consider this diagnosis to avoid missing a potentially fatal condition.
  • Pulmonary Embolism: A large pulmonary embolism can cause right-sided heart failure, leading to ascites. This diagnosis is critical to consider due to its high mortality rate if left untreated.

Rare Diagnoses

  • Familial Amyloid Polyneuropathy: This rare condition can cause restrictive cardiomyopathy, leading to CHF symptoms, including ascites.
  • Sarcoidosis: Sarcoidosis can cause restrictive cardiomyopathy or constrictive pericarditis, leading to CHF symptoms, including ascites.
  • Hemochromatosis: This rare genetic disorder can cause restrictive cardiomyopathy, leading to CHF symptoms, including ascites.
