Differential Diagnosis for Flu-like Symptoms and Mucus Discharge from Ear in Peds

• Single Most Likely Diagnosis
  • Acute Otitis Media (AOM): This is the most common cause of ear discharge in children, often accompanied by flu-like symptoms such as fever, irritability, and sometimes a cough. The mucus discharge is typically a result of the middle ear infection.
• Other Likely Diagnoses
  • Upper Respiratory Tract Infection (URTI): Children with URTI can present with flu-like symptoms and may have ear discharge due to Eustachian tube dysfunction.
  • Allergic Rhinitis: Can cause Eustachian tube dysfunction leading to ear fullness and discharge, especially if there's associated postnasal drip.
  • Sinusitis: Often presents with flu-like symptoms and can cause Eustachian tube dysfunction, leading to ear discharge.
• Do Not Miss Diagnoses
  • Mastoiditis: A serious complication of AOM that can present with ear discharge, fever, and flu-like symptoms, but also signs of mastoid area inflammation.
  • Petrous Apicitis: A rare but serious complication of otitis media, presenting with severe headache, fever, and ear discharge.
  • Intracranial Complications of Otitis Media: Such as brain abscess or meningitis, which are rare but life-threatening and require immediate attention.
• Rare Diagnoses
  • Cholesteatoma: A type of skin cyst in the middle ear that can cause chronic ear discharge, but it's less common in the context of acute flu-like symptoms.
  • Nasopharyngeal Carcinoma: Extremely rare in children, but can cause Eustachian tube obstruction leading to ear discharge.
  • Immunodeficiency: Certain immunodeficiencies can predispose children to recurrent or severe infections, including those causing ear discharge and flu-like symptoms.
