Case Summary:
An 11-month-old female neutered Ragdoll cat was presented for focal seizures, aggression and altered behaviour. A diagnosis of a nasal dermoid cyst with intracranial extension was made following MRI, cytology and histopathology. The cyst was surgically excised with a resolution of clinical signs, with the exception of ongoing seizure activity requiring anti-seizure medication.
Relevance And Novel Information:
To our knowledge, this is the first reported case of a nasal dermoid cyst in a cat, and the first reported case in the veterinary literature of any species with a nasal dermoid cyst presenting with neurological signs.

Nasal Cannula
A nasal cannula is a lightweight tube split at one end into two prongs and placed in the nostrils. It is typically used to deliver low to medium levels of oxygen.
Suggested flow rate: The suggested flow rate for a nasal cannula typically ranges between 1 and 6 L/min.

Antibody Structure
Antibodies, also known as immunoglobulins (Ig), are essential players of the adaptive immune system. These antigen-binding proteins are produced by B cells and make up 20 percent of the total blood plasma by weight. In mammals, antibodies fall into five different classes, which each elicits a different biological response upon antigen binding.
