INTRODUCTION The abducent nucleus is located in the upper part of the rhomboid fossa beneath the fourth ventricle in the caudal portion of the pons.

A 52-year-old Japanese woman complaining of horizontal double vision for 10 days was admitted to our hospital. Neurological examination revealed left abducent nerve palsy and muscle swelling in her thighs. Brain MRI showed obstruction in the spinal fluid space of the left Dorello's canal, which transmits a portion of the abducent nerve. In Ga-67-enhanced citrate scintigraphy, wide accumulation ...

Abducent palsy, a dysfunction of cranial nerve VI causing diplopia, has an annual population incidence of about 11 per 100 000, of which 3% follow neurosurgery. About 60% of patients with isolated abducent palsy from vascular causes recover within 9 months. Diplopia can significantly affect the person’s quality of life, making simple everyday tasks difficult to manage and even dangerous. Acupun...

Leptospirosis, a disease of great significance in tropical countries, presents commonly as a biphasic illness with acute febrile episode in the first phase followed by a brief afebrile period and then by the second phase of fever with or without jaundice and renal failure. However, it has varied manifestations and unusual clinical features ascribed to immunological phenomena can occur due to th...

Pituitary apoplexy is a serious condition, which if left untreated, might lead to irreversible life-long complications. Hence, pituitary should always be included in the differential diagnoses of patient with an isolated sixth cranial nerve (CN) palsy. This report highlights case presenting CN palsy associated apoplexy. Although adenomas are common, they seldom present abducent without any othe...

BACKGROUND AND PURPOSE The abducent nerve is difficult to identify reliably and consistently with conventional radiologic techniques. In this study, a 3D fast asymmetrical spin-echo MR imaging technique was used to obtain detailed images of the abducent nerve in normal volunteers. METHODS The 3D fast asymmetrical spin-echo MR protocol was used to image the abducent nerves in 24 normal volunte...

The purpose of the study was to evaluate the usefulness of magnetic resonance (MR) in imaging of the cisternal and petroclival segments of the abducent nerve. Heavily T2-weighted submillimetric 3D sequence in axial plane, T1-weighted 3D, 1.5 mm slice thickness sequence in axial plane and TOF sequence were performed on 16 volunteers. Additionally the reformatted T2-weighted images in sagittal an...

BACKGROUND Trigeminal neuralgia (TN) is the most common type of facial neuralgia with incidence of 26.8/100,000 person year. In general, this scenario is characterized by a lancinating, unilateral, paroxysmal pain in the area of the fifth cranial nerve. Several treatment methods, including the injection of ethyl alcohol or butyl alcohol into the ganglion, the glycerol injection into the trigemi...
