RT Journal Article SR Electronic T1 Glioblastoma Multiforme Causing Calvarial Destruction: An Unusual Manifestation Revisited JF American Journal of Neuroradiology JO Am. J. Neuroradiol.

YR 2004 UL http://www.ajnr.org/content/25/9/1533.abstract AB Summary: This report describes invasion of overlying calvaria and soft tissues by a high-grade glioma without macroscopic evidence of dural involvement. The initial radiologic examinations demonstrated a heterogeneous mass in the right frontoparietal region with both extra- and intra-axial components. Inward displacement of the adjacent dura initially prompted consideration for extra-axial lesions such as metastatic lesions, lymphoma, or an aggressive meningioma. The pathologic findings demonstrated a glial cell origin.
