Chronic invasive fungal sinusitis: a report of two atypical cases.
The purpose of this article is to describe a chronic variant of invasive fungal sinusitis (IFS) and discuss its management. This is a retrospective review of two cases of IFS that were characterized by atypical clinical courses. Patient 1 was a 75-year-old man with noninsulin-dependent diabetes mellitus who came to us with a 5-month history of headache. Computed tomography detected an opacified left sphenoid sinus. After the man failed to respond to medical therapy, he underwent a left endoscopic sphenoidotomy. Pathologic examination revealed that septate, branching fungal hyphae had invaded the soft tissues. The patient was started on oral itraconazole, but later switched to intravenous amphotericin B in response to intracranial extension. The man's disease stabilized, but he died a little more than 1 year later of unrelated causes. Patient 2 was an otherwise healthy 41-year-old woman who came to us with nasal congestion and unilateral nasal polyps. She underwent endoscopic sinus surgery. Pathologic examination identified granulomatous sinusitis and septate, branching fungal hyphae that had invaded the soft tissue of the middle turbinate. The patient was not treated with systemic antifungal medications because of the localized nature of the fungal invasion and the lack of bone invasion or erosion. She has now been symptom-free for 5 years. These two cases demonstrate that IFS can appear in a chronic variant form that is characterized by an indolent course and histologic evidence of tissue invasion by fungal hyphae. The type of treatment is dependent on the extent of the disease on initial examination and the rapidity of its progression.
