- Fig 1.
Images from the case of a 43-year-old man who experienced an abrupt and severe right-sided frontal headache that occurred with the descent of a commercial jet airplane and became excruciating at the time of landing. Imaging showed that a polypoid mass was present in the right frontal sinus.
A, Axial view spin-echo T1-weighted MR image obtained through the frontal sinuses. A rounded mass in the right frontal sinus (arrow), which was hyperintense on both sequences, was consistent with submucosal hemorrhage.
B, Fast spin-echo T2-weighted MR image.
- Fig 2.
Axial view T1-weighted MR image obtained at a follow-up study 2 months later. Only a small remnant is seen (arrow). Note that because of differences in angulation of the axial plane, the brain morphology is different from that shown in Figure 1 but the morphology of the frontal sinus is similar.
