Sangsaard S A 75-year-old woman presented with fever and right temporal, periorbital and facial pain
for 7 days. Physical examination revealed an ipsilateral paresis of the superior division of the
oculomotor nerve with mild exophthalmos. She also had hyperglycemia. CT scan of the paranasal
sinuses showed acute sinusitis. Rhinoscopy demonstrated black necrotic tissue in the nasal septum.
KOH preparation of tissue biopsy specimen revealed large, non septate hyphae with right angle
branching, diagnostic of rhinocerebral mucormycosis. She was treated with amphotericin B, sur-
gical debridement and insulin therapy. Surgical tissue specimen also confirmed mucormycosis. She
improved after treatment, but 4 months later, ptosis and upward palsy still persisted.
