| Abstract: | Objective To study CT and MRI signs and features of congenital pineal cyst.Materials and Methods CT and MRI findings in 38 cases with congenital pineal cyst were retrospectively analyzed.Results The lesion in all cases presented as a cystic mass with an intact, smooth and sharp cystic wall which showed no abnormal enhancement. The signal intensity and CT value of the cyst wall were similar to those of gray matter of the brain. The cystic fluid displayed water signal intensity of long T 1 and long T 2, with its CT value similar to CSF.Conclusion MRI is an effective method for the diagnosis of congenital pineal cyst. |
