Trigeminal neuropathy arising from the Meckel cave and cavernous sinus is frequently due to meningiomas, trigeminal schwannomas, epidermoid cysts, metastases, pituitary adenomas, and aneurysms. Malignant tumors, which may demonstrate perineural tumor spread, are the most common extracranial cause. A 63-year-old man presented with the loss of the sensations of pain and temperature sensation in the right facial region innervated by the trigeminal nerve (V1 to 3). He showed abnormal lesions in the pons and the trigeminal nerve on magnetic resonance imaging (MRI). He had recurrent herpes in the nasal cavity, and a history of left facial palsy. The aim of the study was to determine the frequency of structural lesions diagnosed on magnetic resonance imaging (MRI) in a sample of patients with trigeminal neuralgia (TN) and to compare history and clinical features between the groups with and without structural lesions. The purpose of this article is to review trigeminal nerve anatomy and to provide strategies for radiologists to recognize important MRI findings in patients with trigeminal neuralgia.

ITNmn commonly affected not only the second and third divisions (86% and 57%, respectively) but also the first division (71%). The most common findings on MRI were enlargement and gadolinium enhancement of the trigeminal nerve, which were similar to those seen in neoplasms (100%). The abnormalities spontaneously regressed in all five evaluable cases.

The trigeminal nerve is the fifth cranial nerve responsible for sensation in the face. It exits the brain on the lateral surface of the pons, entering the trigeminal ganglion from there dividing into three major branches: the ophthalmic branch which controls the orbital area, the maxillary branch which controls the maxillary area and the mandibular branch which controls the mandibular area.

MRI may help to reveal the compression of the trigeminal nerve by vessels. Trigeminal neuralgia (tic douloureux) is a disorder of a nerve at the side of the head, called the trigeminal nerve. This condition causes intense, stabbing or electric shock-like pain in the lips, eyes, nose, scalp, forehead and jaw. Postherpetic neuralgia (PHN) is an unpredictable complication of varicella zoster virus- (VZV-) induced herpes zoster (HZ) which often occurs in elderly and immunocompromised persons and which can induce psychosocial dysfunction and can negatively impact on quality of life. Preventive options for PHN include vaccination of high-risk persons against HZ, early use of antiviral agents, and robust Purpose of Review: Although trigeminal neuralgia is well known to neurologists, recent developments in classification and clinical diagnosis, new MRI methods, and a debate about surgical options necessitate an update on the topic.
