Image a. 3 yr old boy with CNS aspergillosis pt TS. MRI scan pre-amphotericin B
-
Section though unfixed brain showing large pale area of infarction deep in the parietal cortex, in which Aspergillus hyphae were seen histologically. The patient developed disseminated aspergillosis after a prolonged stay in intensive care after contracting severe community acquired pneumonia.
-
The woman had received a renal transplant several months prior to developing a stroke with reduced consciousness. The enhanced CT scan of her brain showed multiple ring-enhancing lesions bilaterally with little surrounding oedema. Biopsy confirmed invasive aspergillosis on histology and culture.
-
Further details
Image A. Multiple ring enhancing abscesses with substantial surrounding oedema was demonstrated. He had no focal neurological deficits. A needle aspiration confirmed the clinical impression of cerebral aspergillosis by culture and microscopy.
Image B. Resolution of cerebral aspergillosis, pt MN. Focal scars with some surrounding oedema are seen in the site of the prior abscesses.

-
Contrast enhanced CT scan of the brain showing unequivocally 2 hypodense lesions, one in the left basal ganglia and one in the right occipital cortex. There is the possibility of another smaller left sided occiptal cortex. These lesions do not have the appearance of abscesses, but rather of ischaema.
-
Unenhanced CT scan of the brain in an allogeneic bone marrow transplant recipient demonstrating a large, variably hypodense lesion in the area of the left basal ganglia and possible additional lesions in the posterior parietal and/or occipital cortex.
-
A. versicolor by microscopy showing very long thin conidiophores.
-
Pigmentation of Aspergillus versicolor colonies ranged from pale green to greenish-beige, pink-green, dark green and brown. Reverse is usually reddish. The growth rate is usually slow. Cultured on Sabouraud dextrose agar with chloramphenicol.
