Plain-English summary
A 4-year-old spayed female Border Collie was taken to the vet because she had a worsening head tilt and trouble walking. Despite treatment, her symptoms didn't improve, and after her owner chose not to pursue further tests, she was euthanized. A necropsy revealed a tumor in her brain that was causing swelling and pressure, leading to serious complications. The tumor was identified as a type of brain cancer called medulloblastoma. Unfortunately, the dog did not recover due to the severity of her condition.

Abstract
A 4-year-old female, spayed Border Collie Dog was brought to the Veterinary Medical Teaching Hospital for evaluation of a progressive head tilt and ataxia that were unresponsive to therapy. Neurologic examination localized a right-sided lesion. The owner refused additional diagnostic tests, and necropsy was performed after euthanasia. Gross findings included atrophy of the temporal muscles and a moderately well delineated, 2.5- x 1.5- x 1.0-cm, gray soft-tissue mass compressing the right cerebellar hemisphere and dorsal hindbrain, resulting in massive dilatation of the lateral, third, and fourth ventricles and hydrocephalus. Histologic examination revealed two distinct features: undifferentiated, primitive, polygonal to fusiform cells with typical morphologic characteristics of medulloblastoma and interspersed areas containing myelinated axons and cells with glial and neuronal differentiation. Immunohistochemical examination confirmed the presence of primitive neuroepithelium and cells with glial and neuronal differentiation.
