The etiological factors involved in idiopathic intracranial hypertension are not easy to identify. This case of idiopathic intracranial hypertension was associated with a capillary hemangioma growing in the lumen of the superior sagittal sinus. ⋯ A tumor growing into a venous sinus is a rare cause of venous outflow impairment and may generate the clinical signs of idiopathic intracranial hypertension. This case emphasizes the importance of multiple complementary imaging modalities and the efficacy of a direct surgical approach, which allowed resolution of symptoms.

The posterior subscapular approach to the brachial plexus is commonly indicated in patients with neural entrapment (neurogenic thoracic outlet syndrome, especially when associated with a large C7 transverse process or cervical rib) and paraspinal tumors or lacerating injuries involving the spinal nerves close to the spine. This approach is also preferred in patients with previous anterior neck operations and/or morbid obesity. We describe the anatomy and operative technique of this approach, which has been used by the senior author (DGK) for the past 25 years.

Case Reports
Thalamic stimulation as a treatment for primary erythromelalgia: technical case report.
We report the use of bilateral thalamic stimulation in a case of primary erythromelalgia with immediate and important pain relief for 3 years. ⋯ We conclude that thalamic stimulation was successful in this case of primary erythromelalgia.

Comparative Study
National trends in surgical procedures for degenerative cervical spine disease: 1990-2000.
Degenerative cervical spine disease is one of the most common indications for spinal surgical intervention. The impact of the unprecedented changes in healthcare technology and delivery over the past decade is unknown. We examined this issue using the Nationwide Inpatient Sample database, a representative sample of all United States inpatient hospitalizations. ⋯ Compared with one decade ago, the surgical treatment of degenerative cervical spine disease has evolved to include a higher percentage of anterior and fusion procedures performed on a more diverse, older, and comorbid patient population, with shortened hospital stay and improved morbidity and mortality, although at substantially increased cost.

The far-lateral approach is an extension of the standard suboccipital approach, designed to maximize exposure of the lateroventral craniocervical junction. Following a basic principle of cranial base surgery, the angle of view is increased by bone removal. Bone removal involves the most lateral part of the inferior occipital squama and the posterior arch of C1. ⋯ Transposition of the vertebral artery is seldom required. The far-lateral approach allows a tangential, unobstructed view of the lateroventral cervicomedullary area and can be applied effectively to manage with a heterogeneous spectrum of pathological lesions involving this area. The technical aspects of the procedure are briefly illustrated in this report.
