A series of nasal endoscopies – before during and after surgery. Surgical endoscopy by Raphaella Migliavacca. A patient 12 years old with AML undergoes remission following chemotherapy (2 rounds), admitted several months later with high fever and neutropenia. Patient undergoes regime of antifungal therapy including fluconazole, AmpB and voriconazole. (see full case as powerpoint slides presented In Brazil In FocusVII Aug 2009 Raphaella Migliavacca.). Nasal endoscopy was performed both pre-operatively and surgery removed a fungal ball. Biopsy revealed suppurative acute inflammatory findings (middle turbinate) and angioinvasive fungal structures consistent with aspergillosis. Cultures revealed Aspergillus flavus. Eight weeks later another endoscopy post surgery revealed marked improvement and reduced inflammation. The patient was given 12 weeks voriconazole followinf the surgery, followed by 3rd chemotherapy. The patient had recovered and was in complete remission 4 months after the surgical endoscopy.
