Cryptococcosis is a potentially fatal fungal infection of mainly the lungs, presenting as a pneumonia, and in the brain, where it appears as a meningitis. [4] [9] Coughing, difficulty breathing, chest pain and fever are seen when the lungs are infected. [5]
There are no specific signs or symptoms that can indicate meningitis, and a lumbar puncture (spinal tap) to examine the cerebrospinal fluid is recommended for diagnosis. [47] Lumbar puncture is contraindicated if there is a mass in the brain (tumor or abscess) or the intracranial pressure (ICP) is elevated, as it may lead to brain herniation.
Meningitis is an unusual manifestation of blastomycosis and can be very difficult to diagnose. Cryptococcus (Cryptococcal meningitis) - it is thought to be acquired through inhalation of soil contaminated with bird droppings. C. neoformans is the most common pathogen to cause fungal meningitis.
Some of the possible symptoms of chronic meningitis (due to any cause) include headache, nausea and vomiting, fever, and visual impairment. Nuchal rigidity (or neck stiffness with discomfort in trying to move the neck), a classic symptom in acute meningitis, was seen in only 45% of cases of chronic meningitis with the sign being even more rare in non-infectious causes.
Important exceptions include cases of Cryptococcal-IRIS with worsening meningitis symptoms (cranial nerve defects, hearing or vision changes) and cases of Kaposi's sarcoma. In these cases, corticosteroids should not be used as they have been shown to worsen outcomes. [3] [4] It is recommended to continue ART except in the most severe cases of ...
Most forms of aseptic meningitis are viral in origin, though neoplastic and Lyme disease meningitis are also aseptic. California encephalitis virus; Central nervous system viral disease; Cytomegalovirus encephalitis; SARS-CoV-2; Eastern equine encephalitis; Enterovirus encephalitis; Epstein Barr Virus encephalitis; Herpes simplex encephalitis ...
Infection begins in the lungs, and from there the fungus can disseminate to the brain and other body parts via macrophages. An infection of the brain caused by C. neoformans is referred to as cryptococcal meningitis, which is most often fatal when left untreated. [5] [29] Cryptococcal meningitis causes more than 180,000 deaths annually. [30]
Cryptococcal meningitis is an infection of the meninx (the membrane covering the brain and spinal cord) by the fungus Cryptococcus neoformans. It can cause fevers, headache, fatigue, nausea, and vomiting. Patients may also develop seizures and confusion; left untreated, it can be lethal. [citation needed]
