Rhinocerebral mucormycosis presenting as oroantral fistula

Abstract

Mucormycosis refers to a severe infection with fungi of order Mucorales, seen in diabetic and immunocompromised patients. Rhino-orbito-cerebral mucormycosis is known to exist in two forms, the well-known acute form and the less well-recognized chronic form. The most common presenting features of the chronic form are ophthalmologic, including ptosis, proptosis, visual loss and ophthalmoplegia. Here, we report a case of chronic rhinocerebral mucormycosis (RCM) presented with nonhealing oroantral fistula in a diabetic patient without any orbital symptoms. We are reporting this case for its unusual presentation.
