Surgical treatment of a canine intranasal meningoencephalocele.
OBJECTIVE
To report the clinical signs, diagnosis, and surgical treatment of an intranasal meningoencephalocele in a dog.


METHODS
Case report.


METHODS
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.


CONCLUSIONS
Meningoencephalocele, although rare, can cause seizures in dogs and can be treated surgically.


CONCLUSIONS
A transfrontal craniotomy with excision of the meningoencephalocele and closure of the defect can be an effective treatment for an intranasal meningoencephalocele in dogs.
