Plain-English summary
A 7-year-old mixed breed dog was experiencing progressive weakness and coordination problems, which led to a veterinary visit. Advanced imaging, specifically magnetic resonance imaging (MRI), revealed two types of spinal cord tumors called hemangiomas. These tumors were characterized by specific appearances on the MRI scans, helping the veterinarians confirm the diagnosis. While the study focused on imaging, it highlights the importance of recognizing these tumors as a potential cause of spinal issues in dogs. Treatment options would typically involve surgery or other interventions, depending on the severity and symptoms.

Abstract
Intramedullary masses are a dilemma due to the limited access for a nonsurgical biopsy, thus, accurate imaging characterization is crucial. Magnetic resonance imaging findings of two confirmed canine thoracic intramedullary hemangiomas are described. A capillary hemangioma was of mixed intensity but predominantly T2-hyperintense and mildly T1-hyperintense to spinal cord with strong contrast enhancement. A cavernous hemangioma had a target-like appearance in both T1-weighted (T1w) and T2-weighted (T2w) images. In T2w images there was a small isointense center surrounded by a relatively large hyperintense area. In T1w images, there was a large isointense centre with a relatively small hyperintense periphery. Such characteristics should prioritize hemangioma as a consideration in a progressive myelopathy due to an intramedullary mass.
