A subsequent MRI revealed a 3.3 x 1.1 cm enhancing soft-tissue mass, hypointense on T1 and hyperintense on T2, in the anterior nasal cavity, medial to the middle turbinate, seeming to originate from the anterior skull base (Figures 1 and 2).

The mass showed multifocal bony dehiscence of the frontal sinuses and left frontal recess with extension into the superior left orbit abutting the superior rectus muscle and globe (Figures 3 and 4).

The treatment was well tolerated; complete remission was achieved; and at last follow-up she had been recurrence-free for 37 months (Figure 5).
