摘要:
目的  探讨松果体先天性囊肿的CT与MRI影像表现及诊断特征。  方法  搜集26 例松果体先天性囊肿病例,回顾性对照分析其CT与MRI表现,研究其诊断特征。  结果  26 例松果体先天性囊肿均表现为圆形或椭圆形, 有完整光滑的囊壁,囊壁信号强度变化或CT值类似于脑灰质,囊壁可有轻微强化改变,囊液为长T1 长T2 水样信号,CT值与脑脊液近似。  结论  CT平扫易遗漏诊断,MRI 诊断松果体先天性囊肿优于CT,特别是矢状位图像, 有助于明确囊肿与第三脑室后部的关系,MRI应作为本病检查的首选方法。
Abstract:
Objective    To study the signs and features of congenital pineal cyst on CT and MRI.     Methods    CT and MRI findings in 26 cases of congenital pineal cyst were retrospectively analyzed.     Results    The lesions in all cases presented as a cystic mass with an intact, smooth cystic wall where enhancement could be seen. The MRI signal intensity and CT value of the cyst wall were similar to those of gray matter of the brain, while signal intensity of the cystic fluid displayed like water with long T1and long T2, and its CT value was similar to that of CSF.    Conclusion    The diagnosis of congenital pineal cyst may be missed if we only refer to CT plain scan. MR images, especially those in sagittal views, are helpful in displaying the relationship of pineal cyst with the posterior part of the third ventricle, so MRI is superior to CT and should be the first choice in diagnosis.
