Plain-English summary
A 7-year-old male Golden Retriever was brought in for symptoms related to hydrocephalus, which is an accumulation of fluid in the brain. After imaging, the vet discovered a medullary dermoid cyst, a type of abnormal growth, that was causing the hydrocephalus. Unfortunately, despite surgical treatment, the dog was euthanized after a follow-up MRI showed no improvement. The postmortem examination confirmed the presence of the cyst but also revealed other uncertain lesions in the brain.

Abstract
Magnetic resonance images were acquired of the brain of a 7-year-old male Golden Retriever with hydrocephalus secondary to a medullary lesion. Images were acquired prior to and 4 weeks following surgical treatment for the hydrocephalus, and the dog was euthanased following the second imaging session. The MR images demonstrated a medullary lesion with patchy but predominantly hyperintense signal with both T1- and T2-weighting, within which small areas of low signal were scattered. There was little edema associated with this lesion and no enhancement with gadolinium. Postmortem examination revealed the medullary mass to be a dermoid cyst. Several small nodular lesions were identified within the central nervous system on the magnetic resonance images whose origin was uncertain on postmortem examination.
