Rhinocerebral mucormycosis: a report of eleven cases.

Rhinocerebral mucormycosis (RCM) is a rare, fulminant fungal infection that usually occurs in diabetic or immunocompromised patients. The mortality rate has been reduced recently with the advent of amphotericin B combined with aggressive surgery. Eleven RCM patients have been treated over the past five years at Srinagarind Hospital. Eight had underlying diabetes, five had renal failure and three of them had both. In eight patients, the diagnosis was established by KOH preparation before histological confirmation. Only two cases revealed positive cultures for Rhizopus spp and Cunninghamella spp. All patients underwent surgical treatments (extensive debridement, 8 cases; sphenoidectomy, 7 cases; ethmoidectomy 8 cases; maxillectomy 5 cases and orbital exenteration, 6 cases). Amphotericin B was administered to all patients as soon as the diagnosis of RCM was made. Only three patients survived. Early diagnosis and cooperation among ophthalmologist, otolaryngologist and physician are the most important factors for the survival of patients with mucormycosis.
