case_images: To confirm the cause of death, a limited brain autopsy was performed, which revealed extensive subarachnoid hemorrhage and aneurysmal dilatation and thrombosis of the basilar artery (BA) [Figure 3].
case_images: Low power photo micrographs taken through the wall of the basilar artery at the site of aneurysm. (a) H and E staining showing dilated and destroyed arterial wall. (b) Elastic Van Gieson staining is showing the loss of internal elastic lamina on the upper part. (c) Gomorri methenamine silver staining is showing an invasive fungal elements from outer to the inner side in the aneurysmal wall. (d) High power photo micrograph showing numerous filamentary infiltrates with an acute angle branching confirming to the morphology of Aspergillus species

case_images: Histopathology of the BA revealed the loss of internal elastic lamina and septate hyphae with an acute angle branching on Grocott's methenamine silver stain, conforming to the morphology of Aspergillus [Figure 4a-d].
