Historical Article
Mind on Canvas: anatomy, signs and neurosurgery in art.
Throughout the ages, art and neuroscience have had a delicate yet definite relationship with reciprocal influence. By virtue of their superior power of observation, artists have often preserved neurological signs through detailed brush strokes or meticulous carvings long before it is described in scientific literature. ⋯ In this article we begin by giving a brief introduction to the general relationship between neuroscience and art as depicted in paintings and drawings, and describe the artistic tendencies of the early neuroanatomists. We aim to highlight the existence of neurosurgical themes within paintings and drawings from different eras.

Case Reports
Delayed cervical spinal cord tethering following tonsillar resection for Chiari malformation.
Although tethering of the spinal cord in the lumbosacral region, particularly following repair of congenital anomalies, such as myelomeningocele, is a well-known phenomenon, only sporadic reports of tethering along the rest of the neuraxis, including the hindbrain, cervical and thoracic spinal cord have been documented. In this report, we describe a woman who developed symptoms related to tethering of the cervical spinal cord 5 years after suboccipital decompressive surgery of the posterior fossa for Chiari I malformation. The authors discuss the diagnosis, treatment, and postoperative course of this entity.

Case Reports
Pelvic teratoma with extensive spinal involvement in a neonate: an important differential diagnosis.
A 6-week-old girl presented with an abdominal mass and spinal cord compression. Clinical and radiological features indicated a diagnosis of congenital neuroblastoma. Histology revealed a diagnosis of germ cell tumour after therapy for neuroblastoma had been commenced. This is, to the authors' knowledge, the first reported case of paediatric dumbbell retroperitoneal teratoma.

The pathogenesis of idiopathic intracranial hypertension (IIH) is poorly understood. Several mechanisms have been suggested, but no one mechanism has been able to account for all manifestations of the disease. Although IIH predominantly affects obese, premenopausal women, little is known about whether or how the obesity contributes to the IIH. ⋯ One potential common pathway linking metabolic disorders to the pathogenesis of IHH is a thrombotic tendency due to dysregulation of haemostatic risk factors. This could cause either occult cerebral sinus thrombosis or partial thrombosis of the parasagittal venous lacunae, with subsequent impaired resorption of cerebrospinal fluid and venous hypertension. Investigations that evaluate obesity, fat metabolism, endocrinological dysregulation and thrombotic tendency in patients with IIH are required so that pathogenic mechanisms can be clarified and management strategies in IIH can be improved.

Multicenter Study
Epidemiology of ventriculostomy in the United States from 1997 to 2001.
Ventriculostomy is a common practice in neurosurgery, but the annual trend of this procedure in the United States has not been reported in the literature. This study evaluates the annual trend during a recent 5-year period. Between 1997 and 2001, a retrospective review was undertaken concerning all patients in the Nationwide Inpatient Sample (NIS) who had undergone ventriculostomy. ⋯ Patient and hospital demographic characteristics were consistent during the study period. By extrapolation of the data, the prevalence of ventriculostomy in the United States averaged 24,380 per year. This study is the first to comprehensively document data concerning the epidemiology of this common procedure.
