Peduncular hallucinosis is characterized by striking visual images, highly colored and mobile, which are recognized by the patient as imaginary. A 50-year-old-man underwent microvascular decompression for a classical right sided trigeminal neuralgia. During the procedure, the petrosal vein and a transverse pontine vein were sacrificed for trigeminal decompression. On the second postoperative day, the patient developed peduncular hallucinosis that disappeared on the forth postoperative day. This is the third case in the literature of peduncular hallucinosis after obliteration of veins of the petrosal venous complex for trigeminal neuralgia. The best policy in cerebellopontine angle surgery is to preserve the petrosal vein whenever possible to avoid complications related to venous congestion.
大脑脚幻觉症的特征是出现鲜明的视觉图像，色彩丰富且可移动，患者意识到这些是虚幻的。一名50岁男性因典型的右侧三叉神经痛接受了微血管减压术。手术过程中，为了进行三叉神经减压而牺牲了岩静脉和一条脑桥横静脉。术后第二天，患者出现大脑脚幻觉症，在术后第四天消失。这是文献中第三例因三叉神经痛而闭塞岩静脉复合体静脉后出现大脑脚幻觉症的病例。在桥小脑角手术中，最佳策略是尽可能保留岩静脉，以避免与静脉充血相关的并发症。
