Refractory cluster-tic syndrome: The Hickam’s dictum

A 50-year-old man debuted with right trigeminal neuralgia. In the following years, it became refractory to medical treatment and ipsilateral cluster headache appeared. He was diagnosed with cluster-tic syndrome. A brain magnetic resonance with high-spatialresolution 3D T2 sequences (FIESTA) excluded the existence of neurovascular conflict, but a surgical exploration was indicated due to its torpid evolution. A venous contact with the right trigeminal nerve was confirmed in the surgery and microvascular decompression was performed. The patient's evolution was favorable, improving the trigeminal neuralgia as well as the cluster headache.
