Plain-English summary
A Miniature Pinscher suddenly became blind and showed changes in behavior. An MRI scan revealed several small fluid-filled areas in the brain, leading the veterinarians to consider various possible causes, including tumors or infections. After further testing, the lesions were identified as a type of cancer called choroid plexus carcinoma, which is rare in dogs. This case adds important information about how these tumors can appear on MRI scans and suggests that they should be considered when dogs have similar brain lesions. Unfortunately, the outcome for this dog was not detailed in the study.
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.
