Plain-English summary
A 5-year-old mixed-breed dog and a 7-year-old Labrador were both experiencing neurological problems due to bleeding in a brain cyst. After imaging tests, both dogs underwent surgery to remove a blood clot and open the cyst. The mixed-breed dog has been doing well and is normal three and a half years later, although the cyst remains. The Labrador initially improved but was later euthanized due to seizures that developed two and a half years after surgery. This suggests that while surgery can help, some dogs may still face complications later on.

Abstract
Clinical signs, magnetic resonance imaging (MRI) features, treatment, and outcome of two adult dogs with neurologic dysfunction resulting from hemorrhage into a quadrigeminal intracranial intra-arachnoid cyst are described. In dog 1, the cyst was hyperintense to cerebrospinal fluid (CSF) on T1-weighted MRI and hypointense to CSF on T2-weighted images. In dog 2, the cyst was isointense to CSF on T1- and T2-weighted images. Both dogs were treated with craniotomy and cyst fenestration. A large blood clot was removed from the lumen of the cyst in each dog. Dog 1 is clinically normal 3.5 years post-surgery and has a persistent cyst. Dog 2 had a good initial response to therapy but was euthanized 2.5 years post-operatively due to generalized seizures. The late onset of clinical signs in these dogs most likely resulted from hemorrhage into the cyst. Surgical fenestration and hematoma removal appear to provide a satisfactory treatment for adult dogs with an intracranial intra-arachnoid cyst and intracystic hemorrhage. Persistence of the cyst may occur in some dogs.
