Fig. 1From: Single internal carotid cavernous sinus aneurysm presented as bilateral painful ophthalmoplegia: a case reportA: an axial contrast-enhanced magnetic resonance image reveals a mass lesion in the left cavernous sinus (arrow). B: Pituitary contrast-enhanced T1-weighted magnetic resonance image shows pituitary compression by the aneurysm (arrow c) and a right shift of pituitary stalk under compression (arrow a). Arrow b shows the pituitary gland. C: Computed tomography angiography shows a large aneurysm in the cavernous sinus segment of the left internal carotid artery about 14.2 × 11.7 mm. D: an axial raw image of computed tomography angiography at the level of biggest diameter of the aneurysmBack to article page
