Plain-English summary
A 12-year-old spayed female Labrador retriever was brought to the vet because she was showing signs of brain problems. An MRI of her brain showed a large fluid-filled cyst in the front part of her brain, which was causing pressure and affecting her brain function. After about two weeks, she suddenly seemed much better, and a follow-up MRI a month later showed that the cyst had shrunk significantly. She lived for over a year before being put to sleep for unrelated reasons, and the cyst was later identified as a cystic meningioma, which is a type of brain tumor. This case is notable because it is the first time a significant reduction in this type of cyst has been reported in dogs.
Abstract
A 12-year-old spayed female Labrador retriever was presented with forebrain signs. Brain MRI revealed a huge cystic lesion with the thickened falx in the frontal region. The brain parenchyma surrounding the lesion showed significant signs of a mass effect and also increased intracranial pressure. However, the dog suddenly became lucid after about two weeks, and an MRI scan one month after the initial study revealed a dramatically shrunken cystic lesion. The dog survived for over a year until it was euthanized for other reasons, and the brain lesion was diagnosed as a cystic meningioma histologically. To the authors' knowledge, this is the first report that described the reduction of the cystic lesion of a cystic meningioma in dogs.
