Differential Diagnosis for 46-year-old Female with Persistent Symptoms

  • Single most likely diagnosis:
    • Viral Upper Respiratory Infection (URI): The patient's symptoms of nasal congestion, sore throat, headache, and fatigue, which have persisted for a week, are consistent with a viral URI. The addition of left ear fullness could be related to Eustachian tube dysfunction, a common complication of URI.
  • Other Likely diagnoses:
    • Acute Sinusitis: The patient's symptoms of nasal congestion, headache, and fatigue could also be indicative of acute sinusitis, especially if the symptoms have persisted or worsened over time.
    • Acute Otitis Media: The left ear fullness and discomfort could be indicative of acute otitis media, an infection of the middle ear.
    • Allergic Rhinitis: The patient's symptoms of nasal congestion and sore throat could also be related to allergic rhinitis, especially if she has a history of allergies.
  • Do Not Miss diagnoses:
    • Bacterial Meningitis: Although less likely, bacterial meningitis is a potentially life-threatening condition that can present with symptoms of headache, fever, and fatigue. It is essential to consider this diagnosis, especially if the patient's symptoms worsen or if she exhibits signs of severe illness.
    • Temporal Arteritis: This condition, also known as giant cell arteritis, can present with symptoms of headache, jaw claudication, and visual disturbances. Although less likely in this patient, it is essential to consider this diagnosis, especially if she has a history of autoimmune disorders.
    • Lyme Disease: If the patient lives in an area where Lyme disease is prevalent, it is essential to consider this diagnosis, especially if she has a history of tick exposure.
  • Rare diagnoses:
    • Nasopharyngeal Cancer: Although extremely rare, nasopharyngeal cancer can present with symptoms of nasal congestion, sore throat, and ear fullness.
    • Relapsing Polychondritis: This rare autoimmune disorder can cause inflammation of the cartilage in the ears, nose, and trachea, leading to symptoms of ear fullness and discomfort.
    • Wegener's Granulomatosis: This rare autoimmune disorder can cause inflammation of the blood vessels, leading to symptoms of nasal congestion, sore throat, and ear fullness.
