Spinal Meningothelial Meningioma in a Dog

The objective of this study is to report clinical, MRI, surgical, and histological findings of spinal meningothelial meningioma in a dog. The study material was a 9 years old, spayed dog with a history of progressive nonambulatory tetraparesis. The dog had intact cranial and spinal reflexes and deep pain perception. Magnetic resonance images revealed a mass located at the left side C2-C3 level, hyperintense in T1W, isointense on T2W, and well contrast enhancing on postcontrast T1. The mass was microsurgically resected and sub-gross. The dog’s neurological status was improved at one week and survived for 15 months without signs of metastasis. Histological and histochemical workup revealed grade I, meningothelial meningioma. Surgical intervention for spinal meningioma can be suggested as the sole treatment in dogs.
