title: Basilar impression in a child with hypochondroplasia.
abstract: A 4-year-old boy with hypochondroplasia presented with delay in gross motor development. Magnetic resonance imaging demonstrated basilar impression with compression at the craniovertebral junction and mild degree of hydrocephalus. Posterior fossa decompression resulted in improvement in neurologic function and relief of hydrocephalus.
