ABSTRACT
Objective To analyse the imaging characters of intracranial malignant teratomas (IMT). Methods The imaging appearances of IMT were analyzed in 15 pathologically proved IMT. MRI were performed on all the 15 cases, CT on 8 of them. Results Thirteen IMT showed as a lobular cyst solid mass with clear borders. The solid portion of IMT displayed iso (6/13) to hypointense(7/13) on T 1WI and iso (2/13) to hyperintense(11/13) on T 2WI. The heterogeneous enhancement was found in 11 cases, homogeneous in 2. Two IMT exhibited as the intrasellar solid lesions involving thalamencephalon. Calcification was found in 8 IMT on CT scan. No fat was demonstrated in the tumor on both CT and MR. Conclusion IMT displays relatively typical appearances on imaging studies. Together with the CT scan, The MR study may make the diagnosis before the operation.
