case_images: Tesla MR system applying T1-weighted (T1W) sequence before and after intravenous administration of gadolinium; T2W sequence was applied as routine 5 mm thick sequence in axial and coronal planes and as 1 mm thick axial constructive interference steady state (CISS) sequence. T2W sequence showed hypointense signal intensity lesion in the left cavernous sinus lateral to internal carotid artery [Figure 1]; the lesion was isointense on T1W sequence.
case_images: Axial constructive interference steady state (CISS) magnetic resonance image (MRI) showing enlarged left cavernous sinus due to a hypointense signal intensity lesion lateral to internal carotid artery (arrow), lesion is extending anteriorly towards the orbital apex.

case_images: Axial CISS image showed the left cavernous sinus lesion as a hypointense signal intensity mass extending towards orbital apex and superior orbital fissure [Figure 2].
case_images: Post-gadolinium enhanced T1-weighted magnetic resonance image (T1W MRI) shows intensely enhancing lesion in the left cavernous sinus (arrow) lateral to medially displaced internal carotid artery. Lesion appears larger as compared to T2-weighted (T2W) coronal image [Figure 1].

case_images: Postcontrast T1W image showed homogenous enhancement of the lesion in cavernous sinus extending towards the orbital apex [Figures 3 and 4].
case_images: Post-contrast T1-weighted (T1W) axial magnetic resonance image (MRI) showing homogenous enhancement of the left cavernous sinus lesion (arrow); lesion is seen extending up to orbital apex as shown by constructive interference steady state MRI.
