Ollie Trezise: The British Toddler Born with Part of His Brain Protruding Through His Nose

Ollie Trezise was born in February 2014 at the University Hospital of Wales in Cardiff with a rare congenital condition called encephalocele. A gap in his skull allowed a portion of brain tissue and the surrounding membranes to protrude outward, forming a prominent, golf-ball-sized swelling on the bridge of his nose.

The defect was first noticed during his mother’s 20-week ultrasound, when doctors detected unexpected soft tissue on the baby’s face. After birth, an MRI confirmed the diagnosis of a frontonasal encephalocele. As Ollie grew, the protrusion became more pronounced, affecting his ability to breathe properly and increasing the risk of infection.

His mother, Amy Poole, from Maesteg in Wales, described him affectionately as her “little real-life Pinocchio.” Despite the challenges, she emphasized that she loved him unconditionally and found him perfect just as he was.

Ollie underwent several complex surgeries. One early procedure opened his nasal passages to improve breathing. In a major operation at Birmingham Children’s Hospital, specialists carefully removed the protruding sac of brain tissue and fluid, closed the skull defect, and began reconstructing his nose and facial structure. The surgery was successful, significantly improving both his appearance and quality of life.

Cases of encephalocele are uncommon, occurring in roughly 1 to 2 per 10,000 births in the UK. Treatment is highly specialized and available at only a small number of centres. Ollie’s medical team noted the rarity of the frontonasal presentation and expressed satisfaction with the outcome of his reconstruction.

Following the operations, Ollie recovered well and continued to develop like other children of his age. His story highlights both the challenges of rare craniofacial conditions and the advances in paediatric neurosurgery and reconstructive techniques that can restore function and appearance.
