Fig. 1 — Images of a 56-year-old man presenting with headache (case 1).

A. The axial unenhanced CT image shows an ill-defined low density lesion abutting the temporal lobe (*).

B. The axial contrast-enhanced CT image demonstrates the lesion to be a well-defined, heterogeneously well-enhanced, rounded and contoured mass.

C. The axial T2-weighted MR image (4000/96 [TR/TE]) shows the lesion to be a well-defined, round mass that is heterogeneously hyperintense to the muscle and there are multiple, hypointense streaks (arrows) within the mass.

D. The axial T1-weighted MR image (500/11) shows an isointense mass. The hypointense streaks on the T2-weighted image are also hypointense.

E. The axial contrast-enhanced T1-weighted MR images (500/11) reveal homogeneous enhancement of the mass that is based on the petrous ridge and it has a dural 'tail' (arrow). The streaks are well enhanced, as same as the other portions of the mass.
