Plain-English summary
A 5-month-old female Border Collie was diagnosed with a rare condition called an intranasal meningoencephalocele, which is a type of brain tissue that protrudes through the nasal cavity. This was confirmed using advanced imaging techniques. The dog underwent surgery to remove the abnormal tissue and repair the area, which successfully stopped her seizures and excessive tearing. After the surgery, her medication was gradually reduced and eventually stopped, and she remained seizure-free for 28 months afterward. Overall, the surgical treatment was effective in resolving her symptoms.
Abstract
OBJECTIVE: To report the clinical signs, diagnosis, and surgical treatment of an intranasal meningoencephalocele in a dog. STUDY DESIGN: Case report. ANIMAL: Female Border collie, 5 months old. METHODS: A right intranasal meningoencephalocele was identified by computed tomography and magnetic resonance imaging. RESULTS: The lesion was approached by a modified transfrontal craniotomy. Surgical closure of the defect at the level of the cribriform plate and removal of extruded brain tissue resulted in regression of lacrimation and coincided with absence of seizuring. Treatment with phenobarbital was gradually reduced and stopped at 7 months after surgery. At 28 months the dog remained free of seizures. CONCLUSION: Meningoencephalocele, although rare, can cause seizures in dogs and can be treated surgically. CLINICAL RELEVANCE: A transfrontal craniotomy with excision of the meningoencephalocele and closure of the defect can be an effective treatment for an intranasal meningoencephalocele in dogs.
