Concurrence of chromosome 6 chromothripsis and glioblastoma metastasis.

abstract：OBJECTIVE:It is well known that larger aneurysm size is a risk factor for poor outcome after surgical treatment of unruptured saccular intracranial aneurysms (USIAs). However, the authors have occasionally observed poor outcome in the surgical treatment of small USIAs and hypothesized that size ratio has a negative imp...
