MRI findings in six dogs with ependymoma of the brain and spinal cord.

ABSTRACT: There are few published descriptions of the MRI appearance of canine intracranial or spinal cord ependymoma. In this multicenter, retrospective, secondary analysis, case series study, three veterinary radiologists independently reviewed and recorded imaging characteristics of MRI studies in six dogs with histopathologically confirmed ependymoma (three intracranial and three spinal cord cases). A consensus was reached when there was disagreement on specific features. All intracranial ependymomas had forebrain location, heterogeneous signal intensity in T1-weighted (T1W) and T2-weighted (T2W) images, heterogeneous contrast enhancement, and hyperintensity in T2W images. Two ependymomas had an intraventricular location; one was intra-axial. Other imaging features included intralesional cyst-li
