Very lethal condtion!95% mortality even with all treatment

Usually affect the immunosuppressed.Fungus is angioinvasive.

Destroys internal elastic layer of medium andlarge vessels and cause thrombosis and

infarcts

68gk160509



Cause of death

Mass effect and herniation due to abscessesand edema

Massive hemorrhagic infarcts

Rupture of mycotic aeurysms

69gk160509



What was the cause of altered sensorium fouryears back?

Does extensive tinea versicolor and invasiveaspergillosis indicate a as yet undiagnosedimmunocompromised condition in this patient,especially to fungal pathogens?

70gk160509



Suspect invasive aspergillosis if there isinvolvement of paranasal sinuses

Can occur in immunocompetent

Aggressive surgical excision, includingmultiple surgeries at multiple sites may berequired.

Start amphotericin B straightaway at high

maintainance doses of 1.5 mg/kg/day…cumulative doses up to 10 grams followed byhigh dose oral itraconazole.

Voriconazole is a better option if patient can

afford.71gk160509
