Orofacial pain as the sole manifestation of syringobulbia-syringomyelia associated with Arnold-Chiari malformation.

摘要

This is a case report of a male patient who presented with orofacial pain for a year as the only manifestation of syringobulbia-syringomyelia associated with Arnold-Chiari malformation. This article places emphasis on the clinical presentation and possible differential diagnoses. The pain was continuous and affected the left side of the face. It was exacerbated by coughing and physical effort, possibly as a consequence of an increase in intracranial pressure. Paroxysmal pain crises developed over this background of continuous pain, compatible with neurogenic trigeminal pain of the left second branch, together with pain episodes similar to cluster headache on the same side. The symptoms were resolved following neurosurgical management with amplification of the foramen magnum.
