Background: The appearance of dumbbell neuroma of the first thoracic root is extremely rare. The extradural component of a T1-dumbbell neuroma may present as an apical mass. The diagnosis of hand weakness is complex and may be delayed in T1-neuroma because of absence of the palpable cervical mass. One-stage removal of a T1-root neuroma and its intrathoracic extension demanded an extended poster...

We performed a retrospective study of 131 patients who underwent microsurgical removal of statoacoustic neuroma at the University of Wuerzburg. Our goal was to evaluate objective audiovestibular findings prior to and after surgery. Our analysis focused on the evaluation of quantitative parameters in speech and pure-tone audiometry and on the reactivity of the vestibular system.

INTRODUCTION Reconstruction of cranial defects is an essential component of skull base surgery as it aids in restoring functionality, providing coverage of intradural structures, and achieving optimal cosmesis. In acoustic neuroma surgery, tumor removal and subsequent reconstruction of the skull base defect are equally important elements. All three approaches utilized in acoustic neuroma surger...

OBJECTIVE The purpose of this study was to compare the diagnostic accuracy of both ultrasonography (US) and magnetic resonance imaging (MRI) for the assessment of Morton neuroma. MATERIALS AND METHODS Our study group was comprised of 20 neuromas from 17 patients, and the neuromas were confirmed on surgery following evaluation with US, MRI, or both US and MRI. The diagnostic criterion for Mort...

BACKGROUND To better understand patterns of occurrence or diagnosis of brain tumours in different segments of the population, we evaluated associations between sociodemographic variables and the relative incidence of brain tumours as part of a multi-faceted case-control study. METHODS The study was conducted at hospitals in three US cities between 1994 and 1998. In all, 489 glioma cases (354 ...
