title: Vanishing glioblastoma after corticosteroid therapy.
abstract: A recurrent right temporal glioblastoma that vanished on MRI after a short course of intense corticosteroid therapy is reported. This was associated with development of new multicentric lesions in the right frontal lobe and right splenium of the corpus callosum. Rapid disappearance of tumor with steroid therapy is frequently associated with lymphoma and is rarely described in high-grade gliomas. Literature review showed that multicentricity and involvement of the corpus callosum are common features of glioblastoma that vanish after corticosteroid therapy.
