case_images: fig1-2050313X241272687
case_images: Nasal endoscopy showed a smooth mass totally occluding the left nasal side extended to the choana (Figure 1).
case_images: Axial CT SCAN shows left mass in the nasal cavity.

case_images: fig2-2050313X241272687
case_images: A computed tomography (CT) scan demonstrated the total opacity of posterior ethmoid cells, extended to the middle homolateral meatus, and reached the inferior part of the middle turbinate (Figure 2).
case_images: Axial T2-weighted MR image shows left posterior ethmoidal mass.

case_images: fig3-2050313X241272687
case_images: Magnetic resonance imaging showed the mass arising from the sphenoethmoidal recess in the hyposignal T1 and the hyposignal T2 with significant enhancement of gadolinium (Figure 3).
case_images: The tumor is PS100 positive.

case_images: S100 were positive (Figure 4). Six months after surgery, the control magnetic resonance showed an absence of tumor recurrence.
