BACKGROUND Primary central nervous system lymphoma (PCNSL) is an aggressive extranodal non-Hodgkin lymphoma confined to the central nervous system. In this article, we report the results of a pilot trial adding rituximab to the established regimen consisting of methotrexate, procarbazine, and lomustine (R-MCP). DESIGN AND METHODS PCNSL patients ≥65 years(More)
UNLABELLED Primary central nervous system (CNS) lymphoma is an aggressive non-Hodgkin lymphoma with poor prognosis. We evaluated pretreatment (18)F-FDG PET as a prognostic marker in primary CNS lymphoma. METHODS Forty-two immunocompetent patients with newly diagnosed primary CNS lymphoma who underwent pretreatment (18)F-FDG PET were retrospectively(More)
BACKGROUND AND PURPOSE Cervical transforaminal blocks are frequently performed to treat cervical radicular pain. These blocks are performed mostly under fluoroscopy, but a CT-guided technique has also been described. The aim of this study was to review the results of CT-guided CSNRB by using a dorsal approach, to describe the contrast patterns achieved with(More)
The unusual and rare case of a 6-year-old boy is reported who presented with an arachnoid cyst located in the cerebellopontine angle incorporating an ectopic piece of choroid plexus tissue. A microneurosurgical cyst wall resection was performed and the plexus tissue identified and removed. The rare occurrence of ectopic choroid plexus tissue within cysts of(More)
Von Hippel-Lindau (VHL) disease is an autosomal dominantly inherited tumour predisposition syndrome with an incidence of 1:36,000 newborns, the estimated prevalence in Europe is about 1-9/100,000. It is associated with an increased risk of developing various benign and malignant tumours, thus affecting multiple organs at different time points in the life of(More)
This study describes the existence and the clinical and electrophysiological features of multi-focal cortical dysplasia in epilepsy patients. Five patients with intractable focal epilepsy are reported. All patients underwent invasive presurgical video-electroencephalography monitoring. Localization of dysplastic areas was based on high-resolution magnetic(More)
Purpose: Evaluation of the benefit of selective venous blood sampling (SVS) for the preoperative identification of parathyroid adenomas with unclear localization in non-invasive diagnostics. Materials and Methods: In a retrospective study, all patients (n = 23) with primary (n = 21) or tertiary (n = 2) hyperparathyroidism were evaluated from 2005 to 2016 at(More)
Meningiomas are the most common primary brain tumours in adults and are therefore relevant for general practitioners. Most meningiomas are benign and neurosurgical resection offers the best chance of cure. However, complete resection is not achievable in many patients. This accounts for a relevant rate of tumour recurrences within 15 years of follow up. In(More)
INTRODUCTION The Wada test has been the gold standard for testing cerebral language localisation during presurgical investigation in the past decades. However, during the last few years a shift has occurred in epilepsy surgery programmes towards the use of non-invasive methods, predominantly functional MRI (fMRI). However, Wada tests are still performed,(More)
A 38 year old gravida 2, para 1 was admitted to our hospital at 38 ? 4 weeks with a 2-week long history of intractable headache of undulating intensity, radiating from the neck to the back of her head. Magnetic resonance imaging (MRI) showed a complete thrombosis of the right sigmoid and adjacent transverse sinus, and a partial thrombosis of the superior(More)
