Plain-English summary
An 8-year-old mixed-breed dog was diagnosed with a spinal meningioma after showing signs of weakness and difficulty walking. Imaging tests revealed a mass in the cervical spinal cord, and surgery was performed to remove the tumor. The dog recovered well after the surgery, and the tumor was classified as a grade I meningioma, which is generally less aggressive. This case highlights the importance of imaging and biopsy for accurate diagnosis of spinal tumors in dogs.

Abstract
Clinical, imaging, and histological features of 8 canine spinal meningiomas, including a cervical cystic meningioma with imaging and intraoperative features of an arachnoid cyst, are described. All meningiomas were histologically classified and graded following the international World Health Organization human classification for tumors. Six meningiomas were located in the cervical spinal cord. Myelography showed intradural/ extramedullary lesions in 3/4 cases. Magnetic resonance imaging revealed hyperintense intradural/extramedullary masses on pre-contrast T1-weighted and T2-weighted images with homogeneous contrast enhancement in 7/8 cases. One dog had a cerebrospinal fluid-filled subarachnoid cavity dorsal to the cervical spinal cord. A spinal arachnoid cyst was diagnosed on imaging, but the histopathological study of the resected tissue revealed a grade I meningothelial cystic meningioma. There were no differences in outcome associated with tumor grade and surgical treatment (6/8). Cystic meningioma should be considered in the differential diagnosis of intraspinal cystic lesions, and biopsy is necessary for definitive diagnosis.
