| Abstract: | Objective To evaluate the value of CT and MR in the diagnosis of cerebral venous malformation. Methods study included five cases with cerebral venous malformation confirmed by carotid angiography underwent CT(plain and contrast) and noncontrast MR. Results Two cases with hemorrhage were showed as hyperdensity or hyperintensity in CT and MR. The typical “caput medusae” appearance was demonstrarted in others by contrast CT and plain MR. Conclusion MR and CT are effective methods for diagnosis and follow-up cerebral venous malformation, but MR is first choice to enclude the cerebral venous malformation in suspected nonsymptom patients. |
