A four-vessel angiogram was performed to investigate the cause of SAH which revealed a 1.8 x 1.6 mm right ophthalmic artery aneurysm (Figure 1).
Right side (pretreatment) and left side (posttreatment). Axial T1 weighted magnetic resonance imaging (MRI) after intravenous administration of gadolinium. (a) Brain showing resolution of the pachymeningeal enhancement (arrow heads); (b) magnetic resonance venogram showing occlusion of the left cortical vein (arrow). Axial fluid attenuated inversion recovery MRI brain (c) showing resolution of subdural hematomas (arrows) on the bilateral convexities; subarachnoid hemorrhages (d) in the bilateral parietal lobes (bidirectional arrow).
