Infections caused by enteroviruses, rabies, adenoviruses, and Nipah and Hanta viruses are discussed. Several studies defined the pattern of MR imaging findings in these disease processes that reflect parenchymal infiltration…
Many viral infections of the nervous system cause stereotyped pathologic features and overlapping clinical and imaging features. Neuroimaging usually offers neuroanatomical localization of the pathology, degree of involvement of the…
Diagnosis of CNS viral infections is challenging; yet, significant progress in laboratory diagnosis of CNS infections has come through applications of serology and polymerase chain reaction (PCR) to CSF and…
Imaging of the vestibulocochlear nerve has evolved dramatically over the past few decades. The imaging specialist now is involved in the diagnosis of far more diagnostic entities than ever before….
Horner’s syndrome (HS) occurs when there is interruption of the oculosympathetic pathway (OSP). This article reviews the anatomy of the OSP and clinical findings associated with lesions located at various…
The glossopharyngeal, vagus, spinal accessory, and hypoglossal cranial nerves can be affected by an acute or chronic process that has an impact on the way the patient presents clinically. Knowledge…
A good examination in facial nerve imaging (CT or MR imaging) depends on a good knowledge of anatomy. Two clinical situations must be considered: imaging of patients with or without…
Imaging of the trigeminal nerve requires a thorough understanding of its anatomy and function, clinical symptoms related to malfunction, and its key pathologies. Because of the nerve’s long course from…
The ocular motor nerves supply motor fibers to the extraocular muscles of the globe and levator muscle of the eyelid and parasympathetic pupillomotor fibers to the ciliary ganglion. Lesions are…
The olfactory system and especially the olfactory bulb (OB) as the first relay in the olfactory system represent highly plastic structures. For example, OB volume partly reflects the degree of…
