BACKGROUND To present our intraoperative low-field magnetic resonance imaging (ioMRI) technique for stereotactic brain biopsy in various intracerebral lesions. METHOD Seventy-eight consecutive patients underwent stereotactic biopsies with the PoleStar N-20/N-30 ioMRI system and data were evaluated retrospectively. Biopsy technique included ioMRI before(More)
Subarachnoid hemorrhage (SAH) often leads to hydrocephalus, which is commonly treated by placement of a ventriculoperitoneal (VP) shunt. There is controversy over which factors affect the need for such treatment. In this study, data were prospectively collected from 389 consecutive patients who presented with an aneurysm-associated SAH at a single center.(More)
To analyze the role of third-generation cephalosporins as prophylactic antibiotics in neurosurgery. We reviewed the literature for data from randomized controlled trials (RCTs) on third-generation cephalosporins compared to other antibiotic regimen in neurosurgery. End point of the RCTs was the occurrence of surgical site infections (SSIs)--data were pooled(More)
OBJECTIVE To describe an association of growth hormone (GH) secreting pituitary microadenomas and empty sella (ES), which has been described in case reports - the underlying mechanisms are unclear. METHODS We retrospectively analyzed patients operated for GH-producing pituitary adenomas between February 2004 and February 2009. Magnetic resonance imaging(More)
OBJECTIVE To assess the potential meteorological influence on the incidence of aneurysmal subarachnoid hemorrhage (SAH). Previous studies used inhomogeneous patient groups, insufficient study periods or inappropriate statistics. PATIENTS AND METHODS We analyzed 511 SAH admissions between 2004 and 2012 for which aneurysmal rupture occurred within the(More)
PURPOSE Spinal epidural hematoma is a rare clinical entity. We present a case of atypical contrast enhancement pattern in a chronic epidural hematoma of the lumbar spine mimicking an extradural tumor. CASE REPORT A 76-year-old man on treatment with oral anticoagulants presented with a 1-month history of lower back pain radiating into his right upper thigh(More)
BACKGROUND Surgical excision is the standard treatment for intracranial meningiomas. Epilepsy is a major cause of morbidity in meningioma patients, but postoperative control of epilepsy is not achieved in a substantial fraction of patients. The purpose of this study was to define risk factors for postoperative epilepsy. METHODS Patients treated for(More)
Involvement of the central nervous system (CNS) is rarely described in malignant mixed Müllerian tumors (MMMTs). Only four intracranial and two spinal cases have been published to date. Here we report two more cases with heterogeneous clinical, radiologic and pathologic features and summarize the available contemporary literature. One patient presented with(More)
OBJECTIVE To evaluate clinical outcome in a 10-year consecutive series of children operated for sellar and parasellar tumors with special focus on neuropsychology and endocrinology. PATIENTS AND METHODS We analyzed 61 children (30 female) under 18 years of age (mean age 9.9, range 1 month-17 years) operated between 2000 and 2010. Medical records were(More)
