Arachnoid cysts of the quadrigeminal cisterna are infratentorial cystic lesions located between the collicular plate and the incisural notch of the tentorium. We report here five cases of quadrigeminal cisterna arachnoid cysts in dogs. In this study, four of the five dogs were male, three showed signs of seizures, and one dog was over 10 years of age. In two of the dogs, cysts were discovered incidentally. In previous reports, most intracranial arachnoid cysts were located in the quadrigeminal cisterna. The presence of cysts should be considered in toy breeds presenting for seizures or ataxia.
四叠体池蛛网膜囊肿是位于小脑幕切迹和中脑顶盖之间的幕下囊性病变。我们在此报告5例犬四叠体池蛛网膜囊肿。在本研究中，5只犬中有4只为雄性，3只出现癫痫症状，1只犬年龄超过10岁。其中2只犬的囊肿是偶然发现的。在既往报道中，大多数颅内蛛网膜囊肿位于四叠体池。对于出现癫痫或共济失调的玩具犬种，应考虑囊肿的存在。
