Abstract
Chiari malformation type II (CM-II) is a hindbrain developmental malformation. Movement
disorders are rarely described as associated with this condition. We describe the
case of a newborn affected by CM-II presenting with head and neck tremors a few days
after myelomeningocele repair surgery. Later, self-resolving episodes of expiratory
apneas arose. Cranial ultrasounds showed progressive ventricular dilatation. She underwent
ventriculoperitoneal shunt followed by craniocervical bony decompression. After surgery,
both apnea and tremors disappeared. This particular presentation of CM-II is very
rare and potentially difficult to diagnose.
