Odontoid Synchondrosis Fracture with Brown-Séquard Syndrome in a Two-year-old Child: A Case Report.

Brown-Séquard Syndrome (BSS) in children is a rare but serious neurological condition that can develop following damage to one-half of the spinal cord due to odontoid synchondrosis fracture. We report a case of a two-year-old girl who presented with difficulty moving her neck, gait abnormalities, and right-side weakness. She had a history of a fall from bed three months earlier. Computed tomography scan and magnetic resonance imaging revealed an incomplete fracture of C2 vertebra, resulting in focal kyphosis and posterior impingement over the craniocervical junction along with significant cord thinning. Considering the patient's age and the incomplete nature of the fracture, a conservative approach was taken, and the patient underwent immobilization in a cervical collar for an extended period, followed by physiotherapy.
