We report a case of granulomatous change of the pituitary stalk caused by Rathke's cleft cyst. A 50-year-old woman complained of thirst and polyuria in December 2000. In January 2001, the patient was suspected to have diabetes inspidus, and MR Imaging showed a suprasellar mass of the pituitary stalk. The mass was totally resected by the trans-sylvian approach. Pathological diagnosis was Rathke's cleft cyst with subsequent granulomatous change. To our knowledge, there have been 11 cases of Rathke's cleft cyst and subsequent granulomatous change. In the literature, diabetes inspidus was not improved by surgical procedures. However, we suggest that the mass should be totally resected, because some cases in literature showed visual disturbance or hypo-pituitarism under observation.
我们报告一例由拉克氏囊肿引起的垂体柄肉芽肿性改变的病例。一名50岁女性在2000年12月出现口渴和多尿症状。2001年1月，该患者被怀疑患有尿崩症，磁共振成像显示垂体柄有鞍上肿块。通过经侧裂入路将肿块完全切除。病理诊断为拉克氏囊肿伴随后续肉芽肿性改变。据我们所知，已有11例拉克氏囊肿伴随后续肉芽肿性改变的病例。在文献中，手术治疗并未改善尿崩症。然而，我们建议应将肿块完全切除，因为文献中的一些病例在观察过程中出现了视力障碍或垂体功能减退。
