A 29-year-old pregnant woman with myasthenia gravis, a condition requiring long-term immune-suppressing medications, died from a widespread fungal infection caused by Cryptococcus. Despite being HIV-negative, her weakened immune system made her vulnerable to this serious infection. An autopsy revealed the infection had spread throughout her body, including her heart, brain, lungs, and kidneys. This case highlights how fungal infections like cryptococcosis can affect people without HIV when their immune systems are compromised by other conditions or medications.
