Example 1: Female, 36 years old. Seizures dizziness six months, hoarseness, swallowing choking 2 months. Physical examination: God clear, uvula right, poor pharyngeal reflex, missed his tongue left, can not whistling, bilateral Babinski sign (+). CT showed a high density of brain stem shadow, showed a uniform enhancement. Magnetic resonance: T_1 circular low signal area in brain stem, uneven intensity, T_2 mixed high signal. Both consider brain stem space-occupying lesions. DSA confirmed a massive basilar artery aneurysm. Example 2: Female, 58 years old. Slow progressive gait unstable half
