Abstract:
Objective To improve the understanding of malignant triton tumor on imaging findings.Methods CT and MRI findings of rare malignant triton tumor in 3 cases confirmed histologically were analysed with review of the literatures.Results 3 tumors included prostatic malignant triton tumor with pulmonary metastatic tumors and neurofibromatosis-I in 1 case,left haunch malignant triton tumor in 1 case and right maxillary sinus malignant triton tumor with destruction of maxillary sinus paries in 1 case.The imaging appearances of tumors were the huge soft tissue mass which strongly suggested malignant tumors,high signal intensity on T2WI,circular septa inside the tumors with low signal intensity.Conclusion Although the qualitative diagnosis of malignant triton tumor depends on pathological examination,CT and MRI play a useful role in diagnosis and differential diagnosis of this tumors.
