Chiari I malformation as part of the Floating-Harbor syndrome?

We report the first case of a patient diagnosed with Floating-Harbor syndrome (FHS) and Chiari I malformation. The 3-year-old girl was of proportional short stature, had delay of language development, conductive hearing loss and a high threshold of pain. Diagnosis of Chiari I malformation may be difficult in FHS patients who present with communication problems. Clinicians following patients with FHS should be aware of a possible relation between FHS and Chiari I malformation.
