Plain-English summary
A 12-year-old spayed female Labrador retriever was brought in because she was showing signs of brain problems, like confusion and changes in behavior. An MRI showed a large cystic lesion in her brain, which was causing pressure and affecting her function. Miraculously, after about two weeks, she became more alert, and a follow-up MRI a month later showed that the cyst had shrunk significantly. She lived for over a year after this improvement before being euthanized for unrelated reasons, and the lesion was identified as a cystic meningioma (a type of brain tumor).

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.
