The association between Arnold-Chiari type 1 malformation and hemihypertrophy has not been appreciated but a few case reports have suggested their association and proposed a common pathogenesis of dysembryoplasia of mesoderm. We report a case of 17 year-old girl presenting with left side hemihypertrophy and scoliosis. Magnetic resonance imaging (MRI) study of brain and spine revealed underlying Arnold- Chiari type 1 malformation and syringomyelia. The purpose of this paper is to emphasize the need for central nervous system evaluation in patients with hemihypertrophy. (J Korean Acad Rehab Med 2008; 32: 481-484)

Neuropathic arthropathy is a chronic and progressive disease of bone and joints. One of the most common causes of neuropathic arthropathy is syringomyelia. Syringomyelia associated with Arnold-Chiari I malformation has been well documented in many reports. We report a case of 76 year-old woman presented with the right elbow joint pain and stiffness. Her symptom was caused by neuropathic arthropathy associated with Arnold-Chiari I malformation and syringomyelia. The purpose of this paper is to emphasize that neuropathic arthropathy requires the evaluation of central nervous system to assess for occult causal lesion. (J Korean Acad Rehab Med 2007; 31: 252-256)
