Neuroradiological findings at diagnosis of the lesion inside the cavernous sinus. Contrast enhanced CT (A), documenting the space occupying lesion in the left cavernous sinus. T1-weighted images documenting the lesion, which is spontaneously hyper-intense (sagittal view; B – white arrow) and has scarce contrast-enhancement (fat suppressed turbo spin echo T1-weighted axial images after contrast enhancement; C). Axial source image from MR-angio ruled out a vascular lesion (D). The mass lesion remained hyper-intense on un-enhanced fat-saturation T1-weighted images (E), strongly hypo-intense on turbo-spin echo fat-saturated T2-weighted images (F), and iso-intense on gradient echo T2*-weighted images (G).
