Unusual aggressive and rapidly growing glioblastoma multiforme - case presentation.

Glioblastoma multiform is one of the most rapidly progressing cerebral tumors and the most aggressive one in our neurosurgical experience. We present the case of a 45 year old patient with very aggressive type of tumor who had come to our service for the following: intense headache, confusion, right hemiparesis installed approximately one month before. IRM scan shows up the presence of a large tumoral mass without a precise border in the left temporal-parietal region which had extended all the way down to the thalamus. The planned intervention used 5-aminolevulinic acid (5-ALA) for the precise removal of the tumor mass, suboptimal because of the risk of lesioning the motor tracts - indicated by the intraoperative electrophysiological monitoring. After surgery the outcome was good with the partial regression of the motor deficit, but only after 3 weeks due to the unexpected tumor growth the neurological status started to decay and even worsened. The patient underwent surgery again with the partial remission of the symptoms although following imagistic controls showed up fast tumor growth once more. He was recommended to oncology service for the beginning of radiotherapy. We consider the evolution and invasion of this tumor in only a 3 weeks period being impressive. [ABSTRACT FROM AUTHOR]
