Trigeminal neuralgia caused by developmental venous anomaly: A case report at Vietduc Hospital

Abstract

A 59-year-old male patient was admitted to the hospital due to a five-year history of continuous left-sided facial pain. Magnetic resonance imaging (MRI) of the brain with 3D T2W and 3D T1W sequences enhanced with contrast agent revealed a development venous anomaly, specifically a large dilated venous anomaly draining into the superior petrosal sinus on the left side, compressing the root exit zone of the cranial nerve. The patient underwent microvascular decompression surgery to relieve the compression of the nerve and had complete resolution of symptoms without the need for pain medication. We recommend routine MRI imaging combined with 3D T2W, 3D TOF MRA, and contrast-enhanced 3D T1W sequences to detect potential vascular compression causing nerve conflict
