ABSTRACT
A 34-year-old female presented with trigeminal neuralgia caused by a venous malformation in the right cerebello-pontine region. Computed tomography and magnetic resonance imaging demonstrated the abnormal draining veins from the venous malformation. The dilated vessels extended around the trigeminal nerve and compressed the root entry zone. Microvascular decompression (MVD) was performed, and her trigeminal neuralgia was completely relieved without neurological deficits. The offending vessel in most cases of trigeminal neuralgia is an arterial branch. Veins may also be associated with trigeminal neuralgia. The present rare case shows that MVD may be useful for the treatment of trigeminal neuralgia associated with venous malformation. Good outcome depends on decompression of the root entry zone without injury to the vessel. Surgical injury in this region can cause severe neurological deficits. Several treatment options should be prepared for the surgery, such as MVD or rhizotomy.
