淋巴细胞性垂体炎（LH）是一种罕见的原发性炎症性疾病，通常在疑似垂体腺瘤的病变手术后诊断。一些影像学特征已被描述，可能允许术前诊断，如对称性腺体肿大，弥漫性对比增强延伸到基底下丘脑的舌头样的方式。我们描述的情况下，LH的病人提出了一个囊性病变与环形对比增强的MR成像。影像学检查中的这种表现似乎并不罕见，在适当的临床背景下，应被视为提示这种疾病的特征之一。
Lymphocytic hypophysitis (LH) is an infrequent primary inflammatory disorder, which is usually diagnosed after surgery for lesions suspected to be pituitary adenomas. Some radiological features have been described that may allow a preoperative diagnosis, such as a symmetric enlargement of the gland with diffuse contrast enhancement extending to the basal hypothalamus in a tongue-like fashion. We describe the case of a patient with LH presenting with the MR imaging of a cystic lesion with ring contrast enhancement. It seems that this appearance in imaging studies is not unusual, and should be considered among the features suggesting this disease in an appropriate clinical context.
