Annotated T2WI demonstrating relationship of the right superior cerebellar artery (SCA) to the trigeminal nerve.
Case Discussion
One of the common causes of trigeminal neuralgia, where MRI is particularly helpful, is compression of trigeminal nerve by loops of superior cerebellar artery or anterior inferior cerebellar artery. This case classically depicts such abnormality. Patient underwent surgery, and diagnosis was confirmed.
