Frequency and size of sphenoid fibro-osseous lesions visualized on head CT
| Group | Frequency (%) | Sizea ± SD (mm) |
|---|---|---|
| SCD (n = 146) | 14 (9.6%) | 14.3 ± 10.2 |
| Control (n = 292) | 6 (2.1%) | 8.85 ± 5.6 |
↵a Size is the maximal axial dimension. There was a statistically significant relationship (P < .001) between presence of SCD and frequency of sphenoid fibro-osseous lesions. There was no statistically significant relationship between lesion size and SCD status (P = .24).
