Dorsal arachnoid web of the thoracic spine associated with an arachnoid cyst and a presyrinx state as an unexplained cause of thoracic myelopathy: illustrative case.

Background: Dorsal thoracic arachnoid web is a rare diagnosis and is not commonly seen in neurosurgical practice. Patients can present with symptoms and signs of thoracic myelopathy in the setting of an arachnoid cyst and a presyrinx state.

Observations: A 57-year-old male with a 10-year history of worsening bilateral leg weakness and chronic back pain re-presented to the neurosurgery clinic after being seen by neurology and orthopedic spine surgery.

The History of the Development and Use of Suction Devices in Neurosurgery.

This article reviews the major devices, individuals, and other historical landmarks in the development of suction in the field of neurosurgery, where the operating fields are characteristically deep and narrow. Our review spans the 159 years since the first use of aspiration in surgery to modern applications. This report exemplifies a comprehensive history of suction, the minute iteration of devices, and the massive impact this technological development has had on medicine and neurosurgery.

Sir Rickman John Godlee-Contributions in Addition to His 1884 Tumor Resection, A Review.

Background: Sir Rickman John Godlee (1849-1925) was widely known for performing the first documented surgery to resect a tumor from the brain.

Methods: The case was performed on November 25, 1884, on a 25-year-old farmer who presented with a left-sided Jacksonian March seizure.

Results: The case was highly publicized because the tumor was localized by Dr.

Incidence of seizures after surgery for supratentorial meningiomas: a modern analysis.

The authors have assessed the incidence of postoperative seizures in 158 patients with supratentorial meningiomas diagnosed by computerized tomography (CT) and/or magnetic resonance (MR) imaging, which theoretically should lead to early diagnosis and treatment and the potential for improved seizure outcome. Univariate chi-square and logistic regression analyses were performed 24 independent variables against the outcome variable of occurrence of a postoperative seizure. The median duration of preoperative seizures was 1 month, considerably shorter than that found in studies conducted prior to the advent of CT and MR imaging.
