Abstract：
The patient is a 41-year-old woman. She presented with vomiting and lightheadedness, and blood tests showed a generalized decrease in pituitary hormones and hyperprolactinemia. A head MRI showed increased signal intensity lesions on FLAIR image in the pituitary stalk, corpus callosum, periventricular area of the fourth ventricle, and superior cerebellar peduncle. The lesions were homogeneously enhanced, and a brain biopsy confirmed the diagnosis of primary diffuse large B-cell lymphoma of the central nervous system, and chemotherapy was started. Although the suprasellar region is a rare site for primary central nervous system lymphoma (PCNSL), it should be diagnosed early by biopsy.
摘要：
患者是一名41岁的女性。她出现呕吐和头晕，血液检查显示垂体激素和高催乳素血症普遍下降。头部MRI显示垂体柄FLAIR图像上的信号强度病变增加，call体,第四脑室的脑室周围区域，和上小脑花梗.病变均匀增强，脑活检证实了中枢神经系统原发性弥漫性大B细胞淋巴瘤的诊断，化疗开始了.尽管鞍上区是原发性中枢神经系统淋巴瘤（PCNSL）的罕见部位，应该通过活检早期诊断。
