Abstract
Simultaneous development of histologically different primary brain tumors aside from phacomatoses or previous irradiation is rare, and its preoperative diagnosis is still difficult. We report two such cases, a 49-year-old male with an acoustic neurinoma and a cerebellar hemangioblastoma and a 69-year-old female with a parietal convexity meningioma and an ipsilateral frontal lobe astrocytoma. The tumors in the first case developed closely, so some local stimulation probably acted as a developmental factor. However, the tumors in the second case developed in distant areas and were considered coincidental.Keywords
