OBJECT Jugular foramen tumors are rare skull base lesions that present diagnostic and complex management problems. The purpose of this study was to evaluate a series of patients with jugular foramen tumors who were surgically treated in the past 16 years, and to analyze the surgical technique, complications, and outcomes. METHODS The authors(More)
Treatment of large petroclival meningiomas causing brain stem compression is surgical removal followed by radiotherapy or radiosurgery if the lesion was partially resected. The management of small petroclival meningiomas is, however, controversial. Clinical observation, radiosurgery and surgical removal are the options of treatment. The natural history of(More)
OBJECT The authors provide a detailed review of the surgical management of trigeminal schwannomas (TSs) and also discuss the best surgical approach based on the surgical anatomy and tumor extension. METHODS A series of 17 patients with TSs who were surgically treated between 1987 and 2008 at the authors' institution is reported. The lesions were small (<(More)
BACKGROUND Local invasion is the hallmark of malignant glioma dissemination. Leptomeningeal dissemination, a serious complication of malignant gliomas, has been increasingly observed. To correlate the physiopathologic mechanisms and the magnetic resonance imaging patterns of neuroaxis dissemination, a classification of malignant glioma dissemination is(More)
Sirs: The clinical and neuropathological aspects of primary lateral sclerosis (PLS) were first described by Charcot [3] in 1865, and since then there has been much discussion over its existence as a nosologic entity [2]. Nowadays, with the development of modern neuropathologic techniques and imaging investigation, the concept of PLS as a separated disease(More)
Some studies have suggested that intravenous iron therapy may be associated with an increased risk of infection. We analyzed the incidence of bacterial infection in 111 hemodialysis patients. Group 1 (n = 39, transferrin saturation <20%) received 10 doses of 100 mg of intravenous iron saccharate, 3 doses per week (28 treatment days); Group 2 (n = 13,(More)
OBJECTIVE The surgical removal of a jugular foramen (JF) tumor presents the neurosurgeon with a complex management problem that requires an understanding of the natural history, diagnosis, surgical approaches, and postoperative complications. Cerebrospinal fluid (CSF) leakage is one of the most common complications of this surgery. Different surgical(More)
The goal of this study was to develop a method to reduce the costs of intraoperative high-field magnet resonance imaging (iMRI). The results of a series of 29 gliomas removed with this technique are presented. A series of 29 patients with brain gliomas were operated on using a low-cost method of high-field intraoperative MRI (Signa 1.5 T. MR Excite, GE(More)
Primary meningiomas of the jugular foramen are extremely rare. There is controversy regarding the management of these tumors. The objective of this article is to analyze the treatment and results in a series of ten cases. From a series of 107 patients that had been operated on for jugular foramen tumors between 1987 and 2005, ten had meningiomas. The(More)
Vestibular schwannomas (VS) are the most common lesions of cerebellopontine angle (CPA) corresponding to 76–91 % of the cases. Usually, these lesions present typical CT and MRI findings. Non-schwannomatous tumors restricted to the internal auditory meatus (IAM) are rare and their preoperative radiological diagnosis may be difficult. This article describes(More)
