| Abstract: | Purpose: To discuss the CT and MRI diagnostic value of tumor of the fourth ventricle. Materials and Methods: 31 cases of fourth ventrical tumors proved by surgery and pathology were reported. 24 cases were evaluated with MRI, 14 cases with CT and 7 cases with both CT and MRI. Results: Amount to medulloblastoma 9 cases, ependymoma 8 cases, choroid plexus carcinoma 3 cases, epidermoid 4 cases, astrocytoma 2 cases, hemangioblastoma 2 cases, ependyma cyst 1 case, cavernous hemangioma 1 case, germ cell tumor 1 case. (1) There were feartures of CT and MRI appearances in the fourth ventricle tumors. (2) The tumors in fourth ventricle there were speciality of age. (3) The source of tumors could help to determine the nature. Conclusion: There are diagnostic and differential diagnostic value for tumors of the fourth ventricle to depend on their CT and MRI appearance. especially MRI. |
