Differential Diagnosis for Recurrent Epistaxis, GI Bleed, and Cardiomegaly

Single Most Likely Diagnosis

  • Hereditary Hemorrhagic Telangiectasia (HHT): This condition is characterized by recurrent epistaxis, GI bleeding due to telangiectasias, and can also involve cardiac manifestations such as cardiomegaly due to high-output heart failure from arteriovenous malformations.

Other Likely Diagnoses

  • Hypertension: Uncontrolled hypertension can lead to epistaxis, GI bleeding (from angiodysplasia or hypertensive gastropathy), and cardiomegaly (left ventricular hypertrophy).
  • Coagulopathy: Conditions like hemophilia or von Willebrand disease can cause recurrent bleeding episodes, including epistaxis and GI bleeding, and cardiomegaly could be secondary to anemia or other related conditions.
  • Vasculitis: Certain types of vasculitis, such as Wegener's granulomatosis, can cause epistaxis, GI bleeding, and cardiomegaly due to inflammation of blood vessels.

Do Not Miss Diagnoses

  • Cancer: Tumors, especially those with metastasis or paraneoplastic syndromes, can cause a wide range of symptoms including bleeding and cardiomegaly. Examples include gastric cancer causing GI bleed and cardiomegaly from metastasis or tumor emboli.
  • Infectious Endocarditis: This condition can cause embolic phenomena leading to epistaxis and GI bleeding, and the infection itself can lead to cardiomegaly.
  • Amyloidosis: Systemic amyloidosis can cause bleeding due to amyloid deposition in blood vessels and can also lead to restrictive cardiomyopathy, presenting as cardiomegaly.

Rare Diagnoses

  • Ehlers-Danlos Syndrome: A group of disorders that affect connective tissues supporting the skin, bones, blood vessels, and many other organs and tissues. Defects in connective tissues cause the signs and symptoms of these conditions, which can include easy bruising, poor wound healing, and cardiovascular problems.
  • Pseudoxanthoma Elasticum (PXE): A rare genetic disorder that causes mineralization and fragmentation of elastic fibers in some tissues, leading to bleeding and cardiovascular issues.
  • Osler-Weber-Rendu Syndrome: Another name for Hereditary Hemorrhagic Telangiectasia, but included here as it might be considered under rare due to its specific genetic and familial implications.
