Also known as: Zygomycosis
- Diabetes (usually poorly controlled)
- Leukemia and lymphoma
- Long-term steroid use
- Metabolic acidosis
- Poor nutrition (malnutrition)
- Use of some medicines
- A sinus and brain infection called rhinocerebral infection: may start as a sinus infection, and then lead to the swelling of the nerves that stem from the brain. It may also cause blood clots that block vessels to the brain.
- A lung infection called pulmonary mucormycosis: pneumonia gets worse quickly and may spread to the chest cavity, heart, and brain.
- Other parts of the body: mucormycosis of the gastrointestinal tract, skin, and kidneys.
- Eyes that swell and stick out (protrude)
- Dark scabbing in nasal cavities
- Mental status changes
- Redness of skin above sinuses
- Sinus pain or congestion
- Coughing blood (occasionally)
- Shortness of breath
- Abdominal pain
- Blood in the stools
- Vomiting blood
- Pain in the upper abdomen or back
- CT scans
- MRI scans
- Blindness (if the optic nerve is involved)
- Clotting or blockage of brain or lung blood vessels
- Nerve damage
- Sinus pain
- Eye swelling
- Any of the other symptoms listed above
Mucormycosis is a fungal infection of the sinuses, brain, or lungs. It occurs in some people with a weakened immune system.
Mucormycosis is caused by a common fungus that is often found in the soil and in dying plants. Most people come in contact with the fungus at some time. However, people with a weakened immune system are more likely to get this infection.
Conditions most commonly associated with mucormycosis include:
Mucormycosis may involve:
Symptoms of rhinocerebral mucormycosis include:
Symptoms of lung (pulmonary) mucormycosis include:
Symptoms of gastrointestinal mucormycosis include:
Symptoms of kidney (renal) mucormycosis include:
Symptoms of skin (cutaneous) mucormycosis include a single, painful, hardened area of skin that may have a blackened center.
Exams and Tests
Your health care provider will examine you. See an ear-nose-throat (ENT) doctor if you are having sinus problems.
Testing depends on your symptoms, but may include these imaging tests:
A biopsy must be done to definitively diagnose mucormycosis.
Surgery should be done immediately to remove all dead and infected tissue. Surgery can lead to disfiguration because it may involve removal of the palate, parts of the nose, or parts of the eye. Without such aggressive surgery, however, chances of survival are greatly decreased.
You will also receive antifungal medicine, usually amphotericin B, through a vein. After the infection is under control, you may be switched to a different medicine.
Mucormycosis has an extremely high death rate, even when aggressive surgery is done. Risk of death depends on the area of the body involved and your overall health.
These complications may occur:
When to Contact a Medical Professional
People with weakened immune systems and immune disorders (including diabetes) should seek medical attention if they develop:
Because the fungi that cause mucormycosis are widespread, the best way to prevent this infection is to improve control of the illnesses associated with mucormycosis.
