case_images: Threshold perimetry (a) and fundus photography (b) of the patient. There is reduced sensitivity in the central visual field, in particular for the right eye. The optic nerve heads appear hyperaemic, and there are peripapillary telangiectasias.

case_images: Threshold perimetry demonstrated reduced sensitivity centrally, in particular for the right eye (Fig. 1a). Her optic nerve heads were hyperaemic, with peripapillary telangiectasias (Fig. 1b).
case_images: Coronal magnetic resonance imaging (MRI) of the patient. The most anterior MRI section (a) shows that the optic nerves (stars) straddle the tumour (T) without being encased. The most posterior MRI section (b) shows the tumour (T), the anterior communicating artery (ACOM) aneurysm, and the posterior communicating artery (PCOM) aneurysm, which compresses the medial temporal lobe.

case_images: Magnetic resonance imaging revealed a tuberculum sellae meningioma lifting the prechiasmatic optic nerves, a 4-mm anterior communicating artery aneurysm, and a 14-mm right posterior communicating artery aneurysm (Fig. 2).
