Abstract
A 12-year-old golden retriever suffering seizures was referred to our department. On the first day of the referral, magnetic resonance imaging revealed a tumor mass in the right olfactory bulb. On the 28th day, the mass was removed via a transfrontal craniotomy. Based on the histopathological findings, the tumor was identified as a histiocytic sarcoma. After surgery, the dog underwent CCNU chemotherapy. On the 195th day, neither progress of the local tumor nor distant metastasis could be detected. On the 278th day, the dog died due to respiratory failure. Surgery and chemotherapy may improve survival for dogs with intracranial histiocytic sarcoma, similar to dogs with lung and limb histiocytic sarcoma.
