title: A surgical approach to the canine olfactory bulb for meningioma removal.
abstract: Olfactory bulb lesions were diagnosed in four dogs presented for generalized seizure disorders. Surgery was performed on each dog using a transfrontal craniotomy. A free fascial-fat graft was used to cover the dural defect resulting from surgery. No major complications were observed during the immediate postoperative period. The histopathologic diagnosis in each case was meningioma. Generalized seizures recurred in all dogs, and three dogs were euthanized for this reason from 9 to 29 weeks postoperatively. One dog was euthanized 12 weeks after surgery due to pancreatitis and pneumonia. Necropsy showed that two dogs had recurrent olfactory bulb meningiomas, one dog had a meningioma of the opposite olfactory bulb, and one dog was tumor free.
