Differential Diagnosis for Warning Leak

• Single most likely diagnosis:
  • Aneurysm: This is the most likely diagnosis because a warning leak is often a symptom of an impending rupture of an aneurysm, which is a balloon-like bulge in a blood vessel.
• Other Likely diagnoses:
  • Arteriovenous Malformation (AVM): AVMs are abnormal connections between arteries and veins, which can cause bleeding and may present with symptoms similar to a warning leak.
  • Vasculitis: Inflammation of the blood vessels can cause weakening of the vessel walls, leading to potential leaks or ruptures.
• Do Not Miss diagnoses:
  • Ruptured Aortic Dissection: Although less common, a ruptured aortic dissection is a life-threatening condition that requires immediate attention. It occurs when there is a tear in the inner layer of the aorta.
  • Hemorrhagic Stroke: Bleeding in the brain can present with sudden onset of symptoms and is critical to diagnose promptly to initiate appropriate treatment.
• Rare diagnoses:
  • Pseudoaneurysm: A false aneurysm that occurs when there is a leak in the artery wall, causing blood to collect outside the vessel.
  • Vascular Tumors: Rare tumors of the blood vessels can cause symptoms similar to a warning leak due to potential bleeding or rupture.
