Abstract: La cirugia del schwannoma vestibular (SV) se inció a finales del siglo XIX. En esa epoca ... se caracterizaba por una elevada morbimortalidad llegando la mortalidad a superar el 20%. Gracias a los avances de las tecnicas quirurgicas, la mortalidad de esta cirugia ha descendido considerablemente, consiguiendose la reseccion tumoral completa y la conservacion de las funciones facial y auditiva en no pocos casos. Una de las complicaciones provocadas por esta cirugia, la mas frecuente en la mayorıa de las series, es la fistula de liquido cefalorraquıdeo (LCR)

Abstract: Magnetic resonance spectroscopy (MRS) offers a variety of procedures to assess the metabolic alterations that occur in cerebral neoplasms, helping to obtain diagnostic decisions in a manner complementary to that provided by classical histopathology. H-MRS has been most widely used in this context, in combination with elaborate statistical approaches, to classify the histological type of the brain tumor and its grade of malignancy. These studies are mainly focused in the profile of water soluble metabolites in vivo or ex vivo, as detected by H MRS or H HRMAS (high-resolution magic angle spinning) ...

Abstract: Discrimination between high and low glioma grade remains avital diagnostic decision, determining the most effective treatment and having an important impact on patient manage-ment and outcome .In vivo HMR spectroscopic examinations are often used in clinical environments to assess tumor aggressiveness and help the MRI-based tumor diagnosis. Auseful parameter in this sense is the total Choline (tCho) versus Creatine (Cr) ratio, which has previously been reported to be related to tumor grade. ...
