background and importance: the coexistence of pituitary adenoma and another type of brain tumor is a very rare clinical scenario. even though such a presentation can be an incidental event but the possible pathogenesis of coexistence of different lesions in the sella and suprasellar region has not yet been elucidated. case presentation: two cases of concomitant sellar and suprasellar region tum...

this report describes the case of a 56 year-old man with a history of diplopia. his brain imaging showed multiple lesions with a metastatic appearance, however all investigations to determine the primary source of malignancy were negative. the patient underwent a brain biopsy, which was positive for anaplastic astrocytoma, a rare tumor that should be considered in the differential diagnosis of ...

 Primary and secondary malignant central nervous system (CNS) tumors are devastating invasive tumors able to give rise to many kinds of differentiated tumor cells. Glioblastoma multiform (GBM), is the most malignant brain tumor, in which its growth and persistence depend on cancer stem cells with enhanced DNA damage repair program that also induces recurrence and resists current chemo- and radi...
