| Patient No. | Sex/ Age (years) | Location | Lesion Size (mm) | Unenhanced CT | MR Imaging | Follow-Up (years) | ||
|---|---|---|---|---|---|---|---|---|
| T1WI | T2WI | Contrast | ||||||
| 1 | F/26 | Nasal septum | 33 | Isodense | Isointense | Hypointense | Moderate | 2 |
| 2 | M/16 | Nasal septum | 52 | Isodense | Isointense | Hypointense | Moderate | N |
| 3 | F/62 | Right lateral nasal wall | 21 | Isodense | Isointense | Isointense | Moderate | 4 |
| 4 | M/28 | Nasal septum | 26 | Isodense | N | N | N | 3 |
| 5 | F/24 | Nasal septum | 35 | Isodense | N | N | N | 5 |
| 6 | M/73 | Left lateral nasal wall | 12 | Isodense | N | N | N | 0.5 |
Note:—Lesion size indicates maximum diameter. CT density and MR imaging signal intensity are compared with cerebral gray matter. N indicates none.
Five patients were followed up for 0.5–5 years following surgery. Patient 1 recurred after 2 years (Fig 3F); the other 5 patients showed no evidence of recurrence. After the second surgery, a follow-up of approximately 1 year for patient 1, there was no clinical evidence of recurrence.
