[Multiple primary brain tumors].

This is a write-up of 32 studies of patients suffering from multiple primary brain tumours. Such tumours are encountered quite rarely. Meningiomas, as well as their combination with tumours of another histological structure (neurinomas, gliomas) were most often studied among multiple primary brain tumours. Multiple gliomas occur even more rarely; they may be of a varying degree of malignancy and different in histological structure. Questions of histological structure, the peculiar features of the clinical picture, diagnosis and surgical treatment of patients with this pathology are discussed. A very rare case of multiple primary sarcomas of the brain is described.
