Título

The Trigemius Nerve: Anatomy and Pathology

Introdução

The trigeminal nerve is the fifth cranial nerve and is a sensory-motor nerve that provides the innervation to the face with its three roots. The trigeminal nerve can be affected by several diseases, such as vascular conflict, congenital malformation, inflammatory or neoplastic diseases. Magnetic Resonance Imaging plays a crucial role in its evaluation. The aim of this pictorial essay is to review the trigeminal nerve anatomy, discuss the most suitable magnetic resonance imaging techniques to evaluate each nerve segment, and demonstrate the imaging aspect of the diseases that most commonly affect it.

Descrição

Objectives: To review the basic anatomy, the magnetic resonance imaging (MRI) imaging technique, and the most commom disorders involving trigeminal nerve (V).

Purpose: In this exhibit we provide a review of anatomy and most commom pathology characteristics of the trigeminal nerve in MRI.

Materials and Methods: Brain MRI images were retrospectively collected from our institutional database.

Conclusion: The trigeminal nerves are the fifth cranial nerves and are sensory-motor nerves that provide the innervation to the face with its three roots. The trigeminal nerve can be affected by a myriad of diseases, and MRI plays an important role in its evaluation.
