Bilateral trigeminal neuralgia due to bilaterally duplicated superior cerebellar arteries

Trigeminal neuralgia (TN) is a chronic pain disorder characterised by paroxysmal intense electric shock or stabbing pain, experienced in the sensory branch distributions of the trigeminal nerve.[1][1] TN presents unilaterally in most cases; bilateral TN has a reported incidence of 1.7%–5%.[1][1]
