Khai, a 9 year old male castrated Samoyed mixed breed dog presented to Cornell University’s Hospital for Animals on April 16, 2009 after having multiple seizures the previous evening. Neurologic examination was consistent with a lesion in the forebrain (prosencephalon). An MRI was performed which revealed a right forebrain lesion most consistent with a meningioma. A craniotomy was performed to remove the mass and obtain a definitive diagnosis. He was treated with anti-seizure medications, chemotherapeutic agents and post-operative radiation therapy. This paper will discuss the diagnosis, treatment modalities, and prognosis of canine meningiomas.
