Differential Diagnosis for ICH, Recurrent Epistaxis, AV Malformation

Single Most Likely Diagnosis

  • Hereditary Hemorrhagic Telangiectasia (HHT): This condition is characterized by the presence of multiple arteriovenous malformations (AVMs) that can lead to recurrent epistaxis and increased risk of intracranial hemorrhage (ICH). The combination of symptoms provided aligns closely with the manifestations of HHT.

Other Likely Diagnoses

  • Von Willebrand Disease: A common bleeding disorder that could explain recurrent epistaxis. While it's less directly linked to AVMs, the bleeding tendency could exacerbate symptoms in the presence of an AVM.
  • Hemophilia A or B: These are bleeding disorders that could lead to increased risk of bleeding, including ICH and epistaxis, especially if there's an underlying vascular malformation.

Do Not Miss Diagnoses

  • Brain Tumors: Certain brain tumors can cause AVMs or lead to ICH. Missing a diagnosis of a brain tumor could have severe consequences.
  • Vasculitis: Inflammatory conditions affecting blood vessels could lead to AVM-like symptoms and increase the risk of ICH and epistaxis.
  • Coagulopathy (acquired or drug-induced): Conditions or medications that affect blood clotting could increase the risk of severe bleeding, including ICH and recurrent epistaxis.

Rare Diagnoses

  • Pseudoxanthoma Elasticum (PXE): A genetic disorder affecting elastic fibers in the body, which can lead to bleeding and vascular complications, including AVMs and potentially ICH.
  • Ehlers-Danlos Syndrome: A group of disorders that affect connective tissues supporting the skin, bones, blood vessels, and many other organs and tissues. Some types can lead to easy bruising, poor wound healing, and potentially an increased risk of vascular rupture or AVMs.
