Plain-English summary
A 5-year-old female mixed-breed dog was found to have an unusual mass on her ovary during a routine check-up. The mass was made up of cells that looked like nerve cells and supportive brain cells. After further testing, the veterinarian diagnosed it as an ovarian neuroglial choristoma, which is a rare type of tumor. While the abstract does not specify treatment or outcome, it's important for pet owners to discuss any findings of masses with their veterinarian for appropriate care and management.

Abstract
Neuroglial choristomas are rare in humans and animals. During a routine medical examination, an ovarian mass was found in a 5-y-old female mixed-breed dog. Histologically, the ovarian mass was well-defined, expansile, and composed of large polygonal cells resembling well-differentiated neurons and scattered smaller cells resembling glial cells. Immunohistochemically, the neuron-like cells were positive for neuronal nuclei; the smaller cells were positive for glial fibrillar acidic protein, oligodendrocyte transcription factor 2, and ionized calcium-binding adaptor protein-1. Ovarian neuroglial choristoma was diagnosed.
