Syringomyelia with quadriparesis in CSF shunt malfunction: a case illustration

Shunt malfunction typically presents with headaches, vomiting, and impaired consciousness. Paraparesis has been rarely reported as the initial manifestation of valve dysfunction.

A 17-year-old boy was admitted with invalidating quadriparesis that after neuroimaging evaluation was found to be produced by communicating syringomyelia attributed to shunt malfunction.

Persistence of the central canal in association with communicating hydrocephalus may lead to the development of communicating syringomyelia. In this context, insufficient drainage of CSF produced by shunt dysfunction may evolve exclusively with symptoms and signs of spinal cord involvement in the absence of the usual cerebral manifestations related to shunt failure.
