Plain-English summary
This study talks about two cases of quadrigeminal arachnoid cysts, which are fluid-filled sacs in the brain, found in a kitten and a dog. The first case involved a 10-week-old male Persian kitten that became less responsive over time and sadly died suddenly. An examination after death revealed that the kitten had a congenital (present at birth) cyst that was pressing on its brain, leading to serious brain issues. The second case was a 2-year-old male Yorkshire Terrier that had a possibly acquired cyst linked to a brain condition called necrotizing encephalitis, which causes inflammation and damage to the brain. These types of cysts are rare in both dogs and humans.
Abstract
Two quadrigeminal arachnoid cysts with different pathogenesis are described in 2 different species. A 10-week-old male Persian kitten with a progressively decreasing level of consciousness died spontaneously. At necropsy, mild internal hydrocephalus, caudal cerebellar coning, and cerebellar herniation through the foramen magnum were associated with a congenital quadrigeminal arachnoid cyst compressing the rostral cerebellum and shifting the entire cerebellum caudally. In contrast, a possibly acquired quadrigeminal cyst was observed in a 2-year-old male neutered Yorkshire Terrier in association with necrotizing encephalitis. Quadrigeminal arachnoid cysts have been rarely reported in dogs and humans.
