As radiologic imaging technology improves and more intricate details of the anatomy can be evaluated, images provide more precise diagnostic information and allow better localization of abnormalities. For example, standard T2-weighted magnetic resonance (MR) imaging sequences adequately depicted only the larger cranial nerves, whereas current steady-state free precession (SSFP) sequences are ca...

BACKGROUND We analyzed the effects of local extension sites on survival in patients with locally advanced maxillary sinus cancer. METHODS The criteria for inclusion in this study were as follows: (1) previously untreated maxillary sinus cancer; (2) squamous cell carcinoma; (3) T4 disease; and (4) curative-intent treatment. The data for 118 patients were obtained from 28 institutions across Ja...

GBS and its MFS variant are acute polyneuropathies that are considered to represent a continuum rather than distinct entities, due to the overlap in their clinical features. Enhancement of the CE roots represents the neuroradiologic hallmark of GBS, while findings of neuroimaging studies in MFS are usually unremarkable. Our purpose was to evaluate the MR imaging findings of polyneuropathy in 17...

Schwannomas are usually characterized by a mass that displays rapid and intense contrast enhancement on computed tomography (CT) and magnetic resonance (MR) imaging. Although some cases are associated with cyst formation, a solid component is nearly always visualized. Schwannomas can be associated with any nerve. Schwannomas of the ninth, 1Oth, and 11th cranial nerves, also called neurinomas of...

Autonomic nerves distribute by a variety of methods. They are recognized as components of all spinal and some cranial nerves, but they also have a strong tendency to exhibit a hitch-hiker relationship to arteries and to other nerves. The perivascular plexuses of the head and neck, and of the thorax and abdomen, are especially typical of peripheral sympathetic distribution. In the parasympatheti...

The development of peripheral nerves was studied in a Japanese marine lamprey, Lampetra japonica, in whole-mount and sectioned embryos from hatching until the earliest ammocoete. Nerve fibers were immunohistochemically stained with a monoclonal antibody against acetylated tubulin. Branchiomeric nerves first developed in a simple metamerical pattern, each associated with a single pharyngeal arch...

Cranial nerve blocks (CNBs) have been used for the acute and preventive treatment of a variety headaches, including migraine. The effectiveness CNBs in migraine is usually observed beyond duration block, possibly due to central pain modulation. most target greater occipital nerve. Other commonly targeted nerves are lesser various branches trigeminal nerve, supratrochlear, supraorbital, auriculo...

We report a case of genetically verified Charcot-Marie-Tooth disease in which the patient had cranial nerve symptoms. CT and MR imaging demonstrated enlargement of several cranial nerves, as well as their skull-base foramina, with faint contrast material enhancement identified.

We report a case of type F botulism in a patient with bilateral but asymmetric neurologic deficits. Cranial nerve demyelination was found during autopsy. Bilateral, asymmetric clinical signs, although rare, do not rule out botulism. Demyelination of cranial nerves might be underrecognized during autopsy of botulism patients.
