Plain-English summary
A 10-year-old female mixed-breed dog was brought in after showing signs of severe neurological issues, including falling over, vocalizing, and having seizures. Unfortunately, her condition worsened, leading to stupor and ultimately death. A post-mortem examination revealed a white mass in her brain that was made up of muscle and collagen tissue, which was causing pressure on the brain. This rare condition, called muscular and collagenous cerebellar choristoma, was diagnosed based on the tissue analysis.

Abstract
This report aims to describe the first case of muscular and collagenous choristoma in a dog. A 10-yr-old female mixed-breed dog presented with lateral recumbence, vocalization, positional vertical nystagmus, divergent strabismus, anisocoria, and status epilepticus. The clinical condition evolved to stupor and ultimately, death. Necropsy revealed a white mass causing an irregular increase in the volume of the cerebellar vermis. In histological analysis, a well circumscribed, unencapsulated mass was observed in the cerebellum, consisting of fibers of striated skeletal muscle and collagen fibers, mostly mineralized. Based on the histopathological and histochemical findings, a diagnosis of muscular and collagenous cerebellar choristoma was made.
