Brain Bioelectric Activity

A Puppy with Cranium Bifidum

An 8-week-old French bulldog puppy presented with seizure activity.

The dog was delivered via a cesarian section at a general practice. Several puppies in the litter had cleft palates and this one was a third of the size of the litter-mates. He was mentally 'dull' but was able to eat, drink, and walk around reasonably normally. He also had a cleft palate.

The puppy had an approximately 4cm diameter fontanelle- essentially the entire alopecic area in the photo- which was soft to the touch.

An animal born with a large soft swelling outside of the calvaria, often on the midline, has a meningocele or meningoencephalocele, the latter having brain tissue within the swelling along with the meninges. The skull defect is often called cranium bifidum.
