Intracranial arachnoid cysts in dogs.

Intracranial arachnoid cyst (IAC) is an infrequently reported developmental disorder seen primarily in small-breed dogs. It usually occurs in the caudal fossa, in the region of the quadrigeminal cistern. Although still considered uncommon, IAC is being recognized more frequently in veterinary medicine, coinciding with the increased availability of magnetic resonance imaging.

The seizuring cat. Diagnostic work-up and therapy.

Practical Relevance: Although seizures occur less commonly in cats compared with dogs, they are one of the most common forms of neurological disease in the feline patient. Cats may experience both focal (partial) and generalized seizures and causes are divided into primary disorders, in which there is no underlying cause (ie, idiopathic epilepsy), and secondary disorders. Cats with secondary seizure disorders have either an underlying structural lesion or metabolic disease.

Levetiracetam as an adjunct to phenobarbital treatment in cats with suspected idiopathic epilepsy.

Objective: To assess pharmacokinetics, efficacy, and tolerability of oral levetiracetam administered as an adjunct to phenobarbital treatment in cats with poorly controlled suspected idiopathic epilepsy. DESIGN-Open-label, noncomparative clinical trial.

Animals: 12 cats suspected to have idiopathic epilepsy that was poorly controlled with phenobarbital or that had unacceptable adverse effects when treated with phenobarbital.
