Neuroimaging for case 3, female, 56y, invasive fungal sphenoid sinusitis (right, VA = no light perception). a: Axial CT scan with expansion and opacification of the right optic canal and optic nerve, which was invaded by fungal organisms. b: Axial, T2-weighted MRI scan showing hypointense signal primarily adjacent to the right optic canal. c: Coronal CT scan showing opacification of the right anterior clinoid process. d: Coronal, T2-weighted, contrast-enhanced MRI scan with abnormal signal in the area of the right orbital apex
