We report a rare case of symptomatic Rathke's cleft cyst with thick calcified wall. Brain CT scans revealed a large cystic mass with round thick calcified wall. In this case, we selected the pterional approach instead of transsphenoidal approach due to the possibility of cystic craniopharyngioma. Histopathologically, it was calcified Rathke's cleft cyst with focal epithelial metaplasia. This case illustrates that calcification of the suprasellar cyst does not always suggest craniopharyngioma and the calcification pattern of Rathke's cleft cyst is different from that of the craniopharyngioma.
我们报告一例罕见的症状性拉克氏裂囊肿，其囊壁增厚且钙化。脑部CT扫描显示一个大的囊性肿块，囊壁呈圆形且增厚钙化。在该病例中，由于存在囊性颅咽管瘤的可能性，我们选择了翼点入路而非经蝶窦入路。组织病理学检查显示为钙化的拉克氏裂囊肿伴局灶性上皮化生。该病例表明，鞍上囊肿的钙化并不总是提示颅咽管瘤，且拉克氏裂囊肿的钙化模式与颅咽管瘤不同。
