Results: 4 cases were geminoma, 3 cases were teratoma, 1 case was choriocarcinoma, 4 cases were glioma, 2 cases were meningiomas, pineoblstoma, neuroblastoma, dermoid cyst and arachnoid cyst each had one case. It maybe very difficult if we diagnosed only through MR signals. Due to the multitude origin of histology, we can diagnose through some special signals, such as adipose, cystic degeneration, hemorrhage and implant dissemination. We can also combined with clinical examination which is help to differential diagnosis.
