Spinal Meningothelial Meningioma In a Dog

Abstract

The objective of this study is to report clinical, MRI, surgical and histological findings of spinal meningothelial meningioma in a dog. Study material was a 9 years old, spayed dog with history of progressive non ambulatory tetra paresis. The dog had intact cranial and spinal reflexes, and deep pain perception. Magnetic resonance images revealed a mass located at left side C2-C3 level, hyperintense in T1W, isointense on T2W, well contrast enhancing on postcontrast T1. The mass was microsurgically resected sub gross totally. 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 a sole treatment in dogs.
