Entire syringomyelia associated with Chiari II malformation and severe scoliosis and hydrocephalus.

Abstract

The syrinx can occur in any region of the spinal cord and is common in cervical and/or thoracic region, and distributing along spinal cord is unusual, especially association with Chiari II malformation and scoliosis. To report a first case of entire syringomyelia associated with Chiari II malformation and severe scoliosis and hydrocephalus. The patient began to experience symptoms of bilateral hand weakness in adulthood. In this patient, MR imaging of the brain and spine showed syrinx along entire spine and hydrocephalus, cerebellar tonsillar herniation, and expansion of the fourth ventricle and posterior cranial fossa. The patient underwent operative treatment to prevent the progression of her neurological deficit. At 12 months' follow-up, the patient's neurological deficit remains stable with the scoliosis left untreated. Foramen magnum decompression, duraplasty and syrinx-shunting are effective methods even to CM II and entire syrinx.
