The cranial MRI showed that the long T1 and long T2 signals of different sizes can be seen in the cerebellopontine angle area on both sides. The right cerebellar, temporal lobe, occipital lobe and the cerebrum falx area showed sporadic distribution, T2 signal shadow. After injecting Gd-DTPA, the distribution of cerebellopontine angle, perioccipital cistern, occipital cistern, cerebral vein, cerebral falx area and right cerebellum, temporal lobe, occipital lobe,
