    Abstract:
    BACKGROUND: Communicating syringomyelia can develop in association with hydrocephalus, with communication between syringomyelia and the fourth ventricle a representative neuroimaging finding. CASE DESCRIPTION: A 51-year-old woman presented with slowly progressive bladder dysfunction and scoliosis. She had a nonfunctioning cerebrospinal fluid shunt that had been placed after birth for neonatal hydrocephalus. Tetraventricular enlargement and a holocord syrinx were noted in neuroimaging findings, while phase contrast magnetic resonance imaging and ventriculography revealed communication between the syrinx and fourth ventricle via a dilated central canal. Placement of a de novo ventriculoperitoneal shunt led to collapse of the syringomyelia, though apparent improvement of clinical symptoms was not obtained. CONCLUSIONS: Communicating syringomyelia can develop as a late complication in patients with shunted hydrocephalus. In the majority of reported cases, shunt revision has been shown to be effective, though some cases require posterior fossa decompression and exploration.
