AbstractBackground: Seizures are considered a clinical sign in dogs with internal hydrocepha-lus but are not found in recent studies. Seizure prevalence due to ventricular enlarge-ment and the prevalence of postoperative seizures in animals is not known.Objectives: To determine seizure prevalence in dogs and cats with idiopathic internalhydrocephalus, to identify risk factors for seizure development, and to determine sei-zure prevalence in a 2-year period after ventriculo-peritoneal shunting (VPS).Animals: Records and MRIs of 197 animals from 2001 to December 2019 wereinvestigated. A total of 121 animals (98 dogs and 23 cats) were included in the study.Methods: A retrospective multicenter case cohort study was conducted. Databaseswere searched for dogs and cats with internal hydrocephalus. MRI and CSF examina-tions were evaluated for signs of additional underlying disorders. Prevalence of sei-zures was estimated for animals showing only hydrocephalus internus. Risk factorswere evaluated according to age, morphometric and morphological findings in thebrain. All animals that underwent surgery were reexamined 2 years after surgery.Results: One hundred twenty-one animals (98 dogs and 23 cats) with internal hydro-cephalus met the inclusion criteria. Seizure prevalence in dogs and cats with internalhydrocephalus was low (1.7%; <5.8% CI 95%). Seizures were not observed in the2-year period after surgery.Conclusion and Clinical Importance: Seizure prevalence in dogs and cats diagnosedwith hydrocephalus internus is low. Seizures in association with VPS do not seem tobe a complication of the procedure.
