Plain-English summary
A six-month-old puppy was brought in for seizures and showed signs of ongoing brain dysfunction. Tests, including an MRI, revealed that part of the puppy's brain was extending into the nasal cavity, which is an abnormal condition called ethmoidal encephalocoele. Despite treatment to manage the seizures, the puppy continued to suffer and was ultimately euthanized due to its distress. A postmortem examination confirmed severe brain damage and the unusual brain structure.

Abstract
A six-month-old puppy was presented for investigation of a seizure disorder. Neurological examination indicated persistent cerebral dysfunction in the absence of any identifiable metabolic disorder and magnetic resonance imaging revealed extension of the rostral lobes of the cerebrum into the nasal cavity. Despite symptomatic treatment, the puppy continued to exhibit seizures and appeared distressed and so was euthanased. Postmortem examination confirmed the abnormal anatomy of the rostral part of the brain and absence of a cribriform plate. There was extensive grey and white matter degeneration plus intraparenchymal haemorrhage in the abnormal brain tissue. The findings are consistent with a diagnosis of ethmoldal encephalocoele--a condition that has not previously been reported in the dog.
