A, B, and C – demonstrating thick and thin-walled blood vessels with the lumen filled with many fungal hyphae and disruption of the vessels wall (Grocott-Gomori's Methenamine 200X); D – Higher magnification showing several fungal hyphae with acute angle branching and frequent septations morphologically consistent with aspergillosis (Grocott-Gomori's Methenamine 400X).
