Image Diagnosis: Allergic Fungal Sinusitis

CASE PRESENTATION A 29-year-old woman presented to our clinic with symptoms of allergic rhinitis for 2 years associated with nasal obstruction for 5 months. On examination, there was broadening of the root of nose (Figure 1) with multiple pale polyps in the left nasal cavity. A computed tomography scan revealed a heterogenous lesion in the left ethmoid, maxillary, sphenoid, and frontal sinuses with thinning of the bony walls (Figure 2). A provisional diagnosis of allergic fungal sinusitis was made, and the fungal debris (Figure 3) and polyps were removed completely. Postoperative histopathology confirmed the diagnosis, and the culture from the specimen grew Aspergillus niger (Figure 4). The patient was started on a steroid nasal spray for three months postoperatively and recovered completely; she was asymptomatic at eight-month follow-up. The patient provided informed consent for inclusion in this report.
