(a) Plain craniogram showed the destruction of the upper rim of the right orbit and the right sphenoid wing. (b and c) Brain plain CT examined in outpatient clinic revealed the mixed density lesion with partial high density and the right frontal skull-base destruction. (d) Brain plain magnetic resonance imaging (MRI) disclosed well-demarcated tumor-like lesion with heterogeneous mixed intensity in T2-weighted image, (e) Brain plain MRI disclosed well demarcated tumor-like lesion with heterogeneous mixed intensity in peripheral low intensity in T2 star image. (f) Brain plain MRI disclosed well-demarcated tumor-like lesion with heterogeneous mixed intensity partially high intensity in diffusion-weighted image. (g) Brain plain MRI disclosed well-demarcated tumor-like lesion with heterogeneous mixed intensity heterogeneous mixed intensity in fluid-attenuated inversion recovery image.

Plain craniogram showed the destruction of the upper rim of the right orbit and the right sphenoid wing [Figure 1a]. Brain plain computerized tomography examined in outpatient clinic revealed the mixed density lesion with partial high density and the right frontal skull-base destruction [Figures 1b and c]. Brain plain magnetic resonance imaging disclosed well-demarcated tumor-like lesion with heterogeneous mixed intensity in T2-weighted image, peripheral low intensity in T2 star image, partially high intensity in diffusion-weighted image, and heterogeneous mixed intensity in fluid-attenuated inversion recovery image [Figures 1d-g].
