a MRI showed the course of the trigeminal nerve by sequence T2, PTA was adjacent to the trigeminal nerve, b on gadolinium-enhanced T1-weighted image, PTA presented lateral course, c on T2-weighted image, left parietal cavernoma with typical rim haemosiderin deposit, d on gadolinium-enhanced T1-weighted image, high-intensity mass of left parietal cavernoma

Moreover, an occasionally left parietal cavernoma was observed, presenting typical findings with a rim of gliosis with haemosiderin deposit surrounding it following previous bleeding (Figs. 1, 2).  
MRA showed PTA with lateral course, originating from the posterolateral aspect of the intracavernous portion of the internal carotid artery, it ran underneath the auditory nerve and continued caudally between the trigeminal nerve and abducens nerve to join the distal basilar artery
