| Abstract: | A 4-year-old female French bulldog presented with a 6-month history of
right-sided head tilt and acute onset ataxia. Magnetic resonance imaging (MRI) showed a
large mass lesion at the cerebellomedullary pontine angle. The dog was able to stand and
walk after beginning symptomatic therapy with prednisolone, acetazolamide and glycerin.
Magnetic resonance imaging 10 months after the first examination indicated slight
expansion of the tumor. The dog was able to walk with continuous symptomatic therapy for
15 months until death, although the head tilt persisted. On postmortem examination, the
gross tumor was slightly larger than when seen on the second MRI scan and was
histopathologically diagnosed as a choroid plexus papilloma. |
