Abstract:
Objective To investigate the role of MRI in diagnosis of primary intracranial teratoma.Methods Nine cases of primary intracranial teratoma proved by operation and pathology were examined by MRI before operation.MRI features were analysed retrospectively.Results The localized and qualitative rates were 100% and 88.8% respectively.The characteristic MRI appearances of primary intracranial teratoma were as follows:(1)The tumor was lobular in shape with clear margin;(2)The tumor had heterogeneous signal intensity ;(3)Inhomogeneous Gd-DTPA enhancement in most of the tumors.Conclusion Multiplanar imaging and Gd-DTPA enhancement in MRI are helpful in diagnosis and differential diagnosis of teratoma.
