Great Hospitals in North America: The Medical College of Wisconsin Neurological Surgery.

The Medical College of Wisconsin Department of Neurosurgery delivers subspecialty adult and pediatric neurosurgical care that is patient-centered, evidence-informed, and value-based. Medical College of Wisconsin research advances the science of neurological disease with the goal of a positive translational effect on clinical care. The department supports an environment of education and scholarship for trainees, faculty, and staff alike.

Methotrexate-induced Leukoencephalopathy without Typical Restricted Diffusion on Diffusion-weighted Imaging and the Utility of Magnetic Resonance Spectroscopy to Support the Diagnosis.

Methotrexate (MTX) is a common antimetabolite agent that is widely used today in treating leukemia, lymphoma, and osteosarcoma. Its use has been associated with leukoencephalopathy causing seizures, paralysis, and even coma. To achieve the best possible outcome, it is important to be able to make a prompt diagnosis.

Safe Use of Tissue Plasminogen Activator in Conjunction with the Integra Camino Bolt for the Drainage of Chronic Subdural Hematoma.

Chronic subdural hematoma (CSDH) is a relatively common condition encountered in a neurosurgical practice. There have been increased efforts in creating different treatment regimens for CSDH to improve patients' outcomes, including the addition of tissue plasminogen activator (tPA) in drains to reduce recurrences. Here, we present the first case report of the safe use of tPA in conjunction with an Integra Camino bolt for maximized drainage of CSDH with a successful neurological recovery and the complete resolution of the hematoma.

A Rare Extra-Axial Midline Tentorial Adult Medulloblastoma with Dural-Tail Sign Mimicking a Meningioma.

Medulloblastomas are categorized as the World Health Organization Grade IV neoplasms. Only 33 cases have been reported of extra-axial, mostly in the cerebellar pontine angle and lateral cerebellar hemisphere, medulloblastomas in the current literature. Our study showcases the first case of an extremely rare presentation of an extra-axial midline tentorial adult medulloblastoma with the dural-tail sign mimicking a meningioma.

A Novel Application of the Integra Camino Bolt for the Drainage of Chronic Subdural Hematoma: A Technical Note.

Chronic subdural hematoma (cSDH) is a common neurosurgical pathology associated with older age and complicated by antiplatelet/anticoagulant therapies. With improving medical care in an aging population, the incidence of cSDH will likely increase over the next 25 years, placing a burden on health care costs. Consequently, a simple and inexpensive treatment option is desirable.

Extent of T1+C Intensity Is a Predictor of Blood Loss in Resection of Meningioma.

Introduction: Surgery for meningioma is associated with significant blood loss. Preoperative embolization has been associated with reduction of blood loss and has been noted to decrease intensity on T1 + contrast sequences. We investigate potential relationships between blood loss and the extent of T1 + contrast intensity.

Intracranial subdural empyema mimicking a recurrent chronic subdural hematoma.

Intracranial subdural empyema (ISDE) is a life-threatening condition. The risk for ISDE increases in patients that have undergone prior intracranial procedures. The non-specificity in its clinical presentation often makes ISDE difficult to diagnose.

To Retain or Remove the Bone Flap During Evacuation of Acute Subdural Hematoma: Factors Associated with Perioperative Brain Edema.

Background: The fate of the bone flap is a significant decision during surgical treatment of acute subdural hematoma (SDH). A general guideline revolves around the surgeon's concern for brain edema. Limited studies, however, have focused on the factors that contribute to perioperative brain edema.

A rare remarkable recovery in a pediatric patient with the bi-hemispheric, transventricular trajectory craniocerebral gunshot wound.

The gunshot wound to the head (GSWH) is associated with a mortality rate of 20-90% in adults and 20-65% in the pediatric population. Due to the high rates of mortality and morbidity, the management of these patients has been a topic of high interest in the neurosurgical community. We present an 18-year-old male suffering a GSWH with the bullet following a transventricular trajectory and crossing the midsagittal plane, creating extensive intracranial injuries.
