Combination treatment for rapid growth of a saccular aneurysm on the internal carotid artery dorsal wall: case report.

Aneurysms arising from non-branching sites of the supraclinoid internal carotid artery (ICA) are considered rare, accounting for only 0.9-6.5% of all ICA aneurysms.

Does intramedullary signal intensity on MRI affect the surgical outcomes of patients with ossification of posterior longitudinal ligament?

Objectives: Patients with cervical ossification of posterior longitudinal ligament (OPLL) are susceptible to cord injury, which often develops into myelopathic symptoms. However, little is known regarding the prognostic factors that are involved in minor trauma. We evaluated the relationship between minor trauma and neurological outcome of OPLL and investigated the prognostic factors with a focus on compressive factors and intramedullary signal intensity (SI).

Acute spontaneous cervical epidural hematoma mimicking cerebral stroke: a case report and literature review.

Spontaneous cervical epidural hematoma (SCEDH) is a rare disease, but can cause severe neurologic impairment. We report a case of a 68-year-old female who presented with sudden onset, posterior neck pain, right shoulder pain, and progressive right hemiparesis mimicking stroke with no trauma history. Initial brain CT and diffusion MRI performed to rule out brain lesion did not show any positive findings.

Prognostic factors and clinical outcomes of acute intracerebral hemorrhage in patients with chronic kidney disease.

Objective: We conducted a retrospective study examining the outcomes of intracerebral hemorrhage (ICH) in patients with chronic kidney disease (CKD) to identify parameters associated with prognosis.

The unusual origin of the sternocleidomastoid artery from the lingual artery.

The sternocleidomastoid (SCM) artery supplying blood to the SCM muscle has different origins according to its anatomical segment. The authors performed cadaveric neck dissection to review the surgical anatomy of neurovascular structures surrounding the carotid artery in the neck. During the dissection, an unusual finding was cited in which the SCM artery supplying the middle part of the SCM muscle originated from the lingual artery (LA); it was also noted that it crossed over the hypoglossal nerve (HN).

Clinical outcomes of halo-vest immobilization and surgical fusion of odontoid fractures.

Objective: In the present study, authors retrospectively reviewed the clinical outcomes of halo-vest immobilization (HVI) versus surgical fixation in patients with odontoid fracture after either non-surgical treatment (HVI) or with surgical fixation.

Methods: From April 1997 to December 2008, we treated a total of 60 patients with upper cervical spine injuries. This study included 31 (51.

Optimal use of the halo-vest orthosis for upper cervical spine injuries.

Purpose: Upper cervical fractures can heal with conservative treatments such as halo-vest immobilization (HVI) and Minerva jackets without surgery. The most rigid of these, HVI, remains the most frequently used treatment in many centers despite its relatively high frequency of orthosis-related complications. We conducted this study to investigate the clinical outcome, effectiveness, patient satisfaction, and associated complications of HVI.

Early Dorsal Midbrain Syndrome Mimicking an Adie's Tonic Pupil.

Background: While tonic pupils have been attributed to various diseases, including syphilis, herpes zoster, orbital trauma, temporal arteritis, endometriosis, and paraneoplastic syndromes, obstructive hydrocephalus has not been implicated.

Case Report: A 36-year-old woman visited a neurology department with a 7-day history of throbbing headache and blurred vision in both eyes. She had early dorsal midbrain syndrome mimicking an Adie's tonic pupil, and cholinergic supersensitivity was demonstrated using topical 0.

Decompressive surgery in a patient with posttraumatic syringomyelia.

Posttraumatic syringomyelia may result from a variety of inherent conditions and traumatic events, or from some combination of these. Many hypotheses have arisen to explain this complex disorder, but no consensus has emerged. A 28-year-old man presented with progressive lower extremity weakness, spasticity, and decreased sensation below the T4 dermatome five years after an initial trauma.

Anterior communicating artery aneurysm related to visual symptoms.

Objective: Intracranial aneurysms are sometimes presented with visual symptoms by their rupture or direct compression of the optic nerve. It is because their prevalent sites are anatomically located close to the optic pathway. Anterior communicating artery is especially located in close proximity to optic nerve.

Lateral ventricular diverticulum extending into supracerebellar cistern from unilateral obstruction of the foramen of monro in a neonate.

A ventricular diverticulum is usually found in patients with long-standing severe obstructive hydrocephalus that may extend into the supracerebellar cistern. The route involved in the supracerebellar extension of the ventricular diverticulum is believed to originate through the tela choroidea of the temporal choroid plexus or of the antral choroid plexus. The authors report a 4-week-old girl with hydrocephalus as a result of unilateral obstruction of the foramen of Monro, which dilated the right ventricle and displaced the midline to the left side, collapsing the contralateral lateral ventricle.

Surgical treatment of two patients with infantile spasms in early infancy.

Early surgery for catastrophic epilepsy may prevent developmental deterioration and minimize functional deficit resulting from the surgical procedure. We report two patients who had infantile spasms and underwent surgery for epilepsy in early infancy (younger than 6 months old). Magnetic resonance imaging showed cortical dysplasia in both patients.

Clinical and electroencephalographic features of infantile spasms associated with malformations of cortical development.
