SUMMARY Conventional imaging protocols are unable to visualize the intraforaminal/canalicular segments of the lower cranial nerves (IX-XII). On the basis of previous successful demonstration of individual cranial nerves within the cavernous sinus by constructive interference in steady-state MR imaging, we describe the use of contrast-enhanced 3D fast imaging employing steady-state acquisition M...

Introduction The incidence of nonmelanoma cutaneous head and neck malignancies is increasing worldwide. In a small percentage of cases, associated perineural spread (PNS) of cranial nerves occurs, resulting in poor prognosis, with a recorded 5-year survival rate of 50% to 64.3%. Patients with clinical PNS from cutaneous head and neck malignancies are treated with surgical resection and postoper...

Sarcoidosis is a multisystem disease with neurological involvement seen in only 5% of patients. Cranial neuropathy is a common mode of presentation. Out of the cranial nerves, seventh cranial nerve either unilateral or bilateral, is usually involved though sarcoidal lesions may implicate every cranial nerve. Other cranial nerves, commonly involved are optic, sensory component of trigeminal and ...

Malignant gliomas are characterized by infiltrative growth of tumor cells, including along white matter tracts. This may result in clinical cranial neuropathy due to direct involvement of a cranial nerve rather than by leptomeningeal spread along cranial nerves. Gliomas directly involving cranial nerves III-XII are rare, with only 11 cases reported in the literature before 2014, including 8 wit...

Otological complications of Ramsay Hunt syndrome include facial paralysis, tinnitus, hearing loss, vertigo, dysgeusia, and skin eruption. The lower cranial nerves sometimes are affected by this neuritis. A case is reported of a man without immune-system impairment who had a cranial mononeuritis with unilateral involment of the VIII and VII cranial nerves after infection with varicella-zoster wi...

the autonomic nervous system consists of a vast range of nerves and ganglions. anatomical studies have demonstrated that the sympathetic innervations of the head and neck are affected by the neurons that ramify from the cranial cervical ganglion (ccg). the ccg is the end of the sympathetic cervical trunk, which runs with the vagal nerve during its cervical course. in this study sixteen adult (2...

We report a case of Guillain-Barré syndrome with enhancement of multiple cranial nerves seen with postcontrast MR imaging. Clinical symptoms and electrodiagnostic studies reflected abnormalities of some but not all of the enhancing cranial nerves.

Involvement of the lower cranial nerves as false localizing signs of intracranial tumour is very rare. A laterally placed posterior fossa meningioma gave rise to contralateral cerebellar ataxia and palsies of the fifth, ninth, and tenth cranial nerves.
