Isolated orbital fungal lesions is an uncommon entity as the already reported cases are secondary to the involvement of paranasal sinuses especially in immunocompetent healthy individuals. Even though it is rare and the paranasal sinuses are the primary site of inoculation of the infective organism, it is a serious infection that may first present to an ophthalmologist. Here, we report a case of an isolated orbital fungal granuloma of a 42-year-old immunocompetent female who exhibited protrusion and watering of the left eye with no vision loss. The patient was diagnosed with an ovoid well-defined solid lesion in the medial extraconal compartment of left eye in magnetic resonance imaging orbit and a hyperdense lesion with erosion of medial orbital wall in computerized tomography nose and paranasal sinus. The patient underwent endoscopic exploration with biopsy which revealed the lesion to be necrotizing fungal granuloma. The patient was put on oral antifungals over a course of 3 months. There was a complete resolution of symptoms at the end of 1-year follow-up.
