A patient with peduncular hallucinosis following microvascular decompression is reported. A 63-year-old woman with trigeminal neuralgia had microvascular decompression through a lateral suboccipital approach. When a venous hemorrhage occurred on the surface of the pons during surgery, the two main tributaries of the superior petrosal vein were sacrificed to obtain a wider operative field. On the 1st postoperative day, the patient had no problems and the pain completely disappeared, but on the 2nd day, both visual and auditory hallucinations developed, which continued until the 5th postoperative day. The nature of the hallucinations was consistent with peduncular hallucinosis. The pathogenesis of this variety of hallucination is discussed.
报道了1例微血管减压术后发生大脑脚幻觉症的患者。1名63岁患有三叉神经痛的女性接受了经枕下外侧入路的微血管减压术。手术期间脑桥表面发生静脉出血时，为获得更广阔的手术视野牺牲了岩上静脉的两条主要分支。术后第1天，患者无异常，疼痛完全消失，但在第2天，出现了视幻觉和听幻觉，并持续至术后第5天。幻觉的性质与大脑脚幻觉症相符。讨论了这种幻觉的发病机制。
