Plain-English summary
A Miniature Pinscher suddenly became blind and showed unusual behavior. An MRI revealed multiple small cystic lesions in the brain, which were later identified as a type of cancer called choroid plexus carcinoma. This case is significant because it adds to the understanding of how these tumors can appear in dogs, even when there are no visible signs of a primary tumor. Unfortunately, due to the aggressive nature of this cancer, the prognosis can be quite serious, and treatment options may be limited.

Abstract
A Miniature Pinscher developed acute blindness and behavioral changes. On magnetic resonance imaging (MRI), there were multiple small intra-axial cystic lesions, and primary differential diagnoses included primary or metastatic neoplasia and neurocysticercosis. These cystic lesions were subsequently diagnosed histopathologically as disseminated choroid plexus carcinoma. This is only the second documented description of this diagnosis in a dog, but both patients had very similar MRI findings. This patient adds to the literature about the MRI characteristics of choroid plexus tumors and indicates that choroid plexus tumor should be considered as a possible cause of small multifocal intra-axial cystic brain lesions in dogs, regardless of whether a primary intraventricular lesion is visible.
