Figures
- Fig 1.
Coronal CT images demonstrating bilateral OC widening (arrows) in both types of REAH: REAHi (A) and REAHsnp (B). Typical sinonasal panopacification is seen in SNP (B), with an additional finding of OC opacification.
- Fig 2.
Coronal CT images demonstrating the dimensions measured for the OC (A) and the TND (B).
- Fig 3.
Mean Harvard CT scores demonstrating that patients with REAHi have significantly lower scores than the other 2 groups of patients.
- Fig 4.
Mean width of the OC in 3 groups of patients. *Statistical significance P < .01.
- Fig 5.
Mean total nasal distance in 3 groups of patients: REAHi, REAHsnp, and SNP.
- Fig 6.
Coronal sections of CT sinus demonstrating a bilateral olfactory cleft lesion. A, Erosion of the cribriform plates (solid arrow). B, T1 postcontrast MR imaging differentiating mucus in the ethmoid and frontal sinuses from the centrally located mass with intermediate enhancement. There is an intracranial component (open arrow), with sparing of the dura.
