Figure 2. (A) T1-weighted sequence: Contrast medium enhancing lesion arising from ethmoidal cells. Red arrow indicates the lesion. (B) T1-weighted sequence: Intracranial expansion of the lesion adjacent to inner orbital wall and left orbital gyri. Red arrow indicates the lesion. (C) T2-weighted sequence: Isointense tumor abutting ethmoidal bone. Red arrow indicates the tumor. (D) T2-weighted sequence: Infiltration of left orbital gyri; arachnoidal spaces are not depicted due to parenchyma’s edema. Red arrow indicates the tumor. (E) FLAIR sequence: Vertical extension of vasogenic edema up to the ipsilateral frontal ventricular horn. Red arrow indicates the edema.
