A little girl who was suffering from chronic mucocutaneous candidiasis also had a cellular immune deficiency and undetectable IgA levels. She was treated continuously for 6 years with ketoconazole at the same dosage of 200 mg/day. She was rapidly clear from infection and did not relapse although her immune abnormalities persisted. During this long-term therapy, voluminous fusiform intracranial aneurysm appeared, causing a paresis of the four limbs. Are they mycotic aneurysms?
