Type I and type IV dermoid sinus with associated cervical spina bifida in a Labrador Retriever mixed breed dog.

After transferring to a specialty centre, diagnostic imaging (CT and MRI) revealed spina bifida at C3 and dermoid sinuses at the level of C3 and T1. Surgery was performed to remove the dermoid sinuses.

Meningiomas in both species grow slowly and have an insidious onset of clinical signs.
