Differential Diagnosis for Hearing Heartbeat in the Ear

  • Single most likely diagnosis
    • Pulsatile Tinnitus: This condition is characterized by a rhythmic sound that synchronizes with the patient's heartbeat, often described as hearing one's own heartbeat in the ear. It is commonly associated with vascular or circulatory issues, making it a plausible explanation for the symptom.
  • Other Likely diagnoses
    • Otosclerosis: A condition where abnormal bone growth in the middle ear causes hearing loss and can lead to the perception of hearing one's heartbeat.
    • Eustachian Tube Dysfunction: Issues with the tube that connects the middle ear to the back of the nose and throat can cause a variety of ear symptoms, including pulsatile sounds.
    • Anemia: Reduced hemoglobin or red blood cell count can lead to increased blood flow, potentially causing the sensation of hearing one's heartbeat in the ear.
  • Do Not Miss (ddxs that may not be likely, but would be deadly if missed.)
    • Atherosclerotic Carotid Artery Disease: Narrowing or blockage of the carotid arteries can lead to pulsatile tinnitus and is a significant risk factor for stroke.
    • Glomus Jugulare Tumor: A rare, benign tumor located in the jugular bulb can cause pulsatile tinnitus due to its proximity to the ear and major blood vessels.
    • Arteriovenous Malformation (AVM): An abnormal connection between arteries and veins can cause a variety of symptoms, including pulsatile tinnitus, and poses a risk of rupture and bleeding.
  • Rare diagnoses
    • Paget's Disease: A condition characterized by abnormal bone destruction and regrowth, which can affect the bones of the middle ear and cause hearing symptoms, including pulsatile tinnitus.
    • Fibromuscular Dysplasia: A rare vascular disease that can cause narrowing or blockage of arteries, potentially leading to pulsatile tinnitus.
    • Superior Semicircular Canal Dehiscence: A rare condition where a portion of the inner ear is exposed to the cranial cavity, causing a variety of auditory and vestibular symptoms, including pulsatile tinnitus.
