摘要

目的：探讨Rathke囊肿的影像学特点。材料与方法：病理证实的Rathke囊肿15例，男6例，女9例，年龄20~47岁，平均35.4岁。所有病例均行MRI平扫和增强扫描，其中12例同时接受CT平扫。分析其CT和MRI表现。结果：病变单纯位于鞍内者8例，鞍内鞍上者3例，单纯鞍上者4例。CT可表现为低密度、等密度或者高密度。MRI信号表现多种多样。一般无明显强化，少数可见囊壁的强化。结论：Rathke囊肿影像学表现多样，CT和MRI有一定的价值。

Abstract

Objective: To explore the neuroradiological features of Rathke’s cleft cyst. Materials and Methods: Fifteen cases of Rathke’s cleft cysts proved pathologically received plain and contrast-enhanced MRI scan. Additionally, of the 15 cases, 12 cases received plain CT scan. CT and MRI image features were analyzed. Results: Eight cases were entirely intrasellar, 3 were intrasellar with suprasellar extensions, and 4 were suprasellar. Hypo-, iso-, hyper-density mass were found in Rathke’s cleft cyst on CT scan. Rathke’s cleft cysts may have different MRI signal characteristics according to the component of the cysts. Commonly no enhancement can be seen, but a small amount has enhanced wall. Conclusion: Rathke’s cleft cysts have various findings in imaging, CT and MRI are valuable examinations. But the diagnosis must be given by pathological examination.
