Plain-English summary
A 6-year-old female spayed German Shepherd mixed-breed dog was brought in for treatment after she suddenly started having seizures and showed changes in her behavior. An MRI found a mass in her frontal lobe, and a CT scan of her head showed some damage to a bone in her skull, but there was no invasion into her nasal passages. The mass was surgically removed, and tests on it showed it was a grade I fibrous meningioma, which is a type of brain tumor. After surgery and radiation therapy, the dog did well and had a good recovery.
Abstract
A 6-year-old female spayed German Shepherd mixed-breed dog was presented for treatment of a frontal lobe mass diagnosed on MRI, after an acute onset of generalized seizures and behavior changes. Computed tomography of the head was performed for radiation therapy planning and revealed concurrent cribriform plate lysis without nasal sinus invasion, and focal lysis of the left ventrolateral cranial fossa. Histopathology of the mass obtained via surgical excision was consistent with a grade I fibrous meningioma. The dog had a good outcome following surgery and radiation therapy.
