Symptoms of Fungal Sinusitis

Common causes or types of sinusitis are bacterial and viral. However, there is still another type of sinus infection that is not so common, the fungal sinus infection or the fungal sinusitis. Cases of fungal sinusitis are quite rare and how fungal sinusitis is treated is different from other types of sinus infection. Since fungal sinusitis is caused by fungal infection, using antiviral medications and/or antibacterial medications will be very useless, since fungal infection will never respond to those medications mentioned.

Symptoms of Fungal Sinusitis

Fungal sinusitis is not the sinus infection itself. Fungal sinusitis has several subtypes and has different distinct signs and symptoms. Here are the subtypes of fungal sinusitis together with different fungal sinusitis symptoms.

  • Fungus Balls – When there is an overgrowth of fungi inside the sinuses, there will be a development of a fungus ball/s or mycetoma in medical term. When there are fungus balls present, symptoms like chronic sinus pain, pressure within the sinuses, nasal congestion and drainage will be felt.
  • Allergic Fungal Sinusitis – There are some cases wherein fungus or fungi causes an allergic reaction inside the sinuses, which is known as the allergic fungal sinusitis. Signs and symptoms of allergic fungal sinusitis include but not limited to inflammation of the sinuses and chronic nasal congestion of not both sides of the nose, but only to one side of the nose.
  • Invasive Fungal Sinusitis – This subtype of fungal sinusitis is a life-threatening one. Invasive fungal sinusitis will more likely develop in individuals who have impaired immune system. Signs and symptoms of invasive fungal sinusitis include but not limited to painful sinuses, fever, cough, purulent discharges from the nose, and a very ill feeling.

If invasive fungal sinusitis is not treated or controlled in a timely manner, there will be a very high risk for the development of life-threatening complications. The fungal infection in invasive fungal sinusitis can spread to the eye socket, which then results to a bulging eye and worse, a permanent loss of vision. From the eye socket, it can possibly progress to the brain and to the central nervous system, which can possibly lead to death.


Fungal sinusitis, regardless on what specific type it is, should be diagnosed properly and treated promptly to prevent complications from happening that can possibly lead to one’s death. Treatments for fungal sinus infection in general can include surgical removal of the fungus and intensive medications.
