Plain-English summary
A 7-year-old spayed female English Cocker Spaniel was brought to the vet after showing signs of being very tired, stumbling, circling, and having two seizures over the past week. Tests showed that there were two masses in her brain: one in a fluid-filled space called the right lateral ventricle and another in the right frontal lobe. Because the outlook for recovery was not good, the owner decided not to pursue further treatment, and the dog was euthanized. A postmortem examination revealed that one mass was a meningioma (a type of tumor on the brain's protective layers) and the other was a choroid plexus papilloma (a tumor in the area that produces cerebrospinal fluid). This case is notable because it is the first time that these two types of tumors have been reported together in a dog or in humans.
Abstract
A 7-year-old spayed female English Cocker Spaniel was examined because of a 1-week history of lethargy, stumbling over objects and circling, and the presence of two tonic-clonic generalised seizures two days before presentation. The neurological signs suggested a lesion involving the right forebrain. Computed tomography revealed the presence of two intracranial masses, one located inside the right lateral ventricle and the other located in the right frontal lobe attached to the falx cerebri. Because of the poor prognosis, the owner refused to continue with the therapy and the dog was euthanised. On postmortem examination one mass was diagnosed histologically as a meningioma and the other as a papilloma of the choroid plexus. Information in the veterinary literature on multiple malignancies affecting the central nervous system is very limited. To the best of the authors' knowledge, the association of meningioma and choroid plexus papilloma has never been reported either in the human or in the veterinary medical literature.
