CT findings at nine years old (A: horizontal section; B: coronal section). CT reveals a clearly defined mass in the left nasal cavity with a maximum diameter of 30 mm and similar radiolucency to bone. The mass is exerting pressure on the lamina papyracea and nasal septum.

Computed tomography (CT) revealed a large, clearly defined mass in the left nasal cavity with a maximum diameter of 30 mm and similar radiolucency to bone (Fig. 1A). The mass was exerting outward pressure on the medial wall of the left orbit and the nasal septum was displaced to the right (Fig. 1B).
CT findings at 13 years old (A: horizontal section; B: coronal section). The mass has increased in size, reaching a maximum diameter of 41 mm. The interior of the left nostril was entirely occupied by the mass, which was pressing against the nasal septum.

CT showed the mass had expanded to a maximum diameter of 41 mm (Fig. 2A). The interior of the left nostril was entirely occupied by the mass, which was pressing against the nasal septum (Fig. 2B).
Pathological findings (hematoxylin and eosin staining). Trabeculae show mainly spindle-shaped cells and no adipose tissue.

In the stroma, hyperplasia was observed, with spindle-shaped cells showing spindle-shaped to elliptical nuclei (Fig. 3).
Post-operative nasal finding. Nasal obstruction was improved.

Nasal obstruction was completely resolved following surgery, and no recurrence has been encountered as of more than 12 months postoperatively (Fig. 4).
