INTRODUCTION
Pituitary adenoma is a common benign tumor representing 8 to 10% of intracranial mass lesions. The compressive optic neuropathy associated with a pituitary adenoma can be clinically indistinguishable from glaucomatous optic neuropathy.
CASE REPORT
A 56-year-old man with no significant past medical history had noticed a rapid decrease in visual acuity for 6 months. Funduscopic examination revealed glaucoma-like bilateral, asymmetric optic cupping. Brain MRI examination revealed a pituitary tumor compressing the optic chiasm.
CONCLUSION
The diagnosis of a compressive optic neuropathy associated with a pituitary adenoma can be difficult, since it often simulates chronic glaucoma. However, several features should alert the clinician to the possibility of a compressive optic neuropathy and prompt neuroimaging, in order to obtain earlier diagnosis and treatment.
引言
垂体腺瘤是一种常见的良性肿瘤，占颅内占位性病变的8%至10%。与垂体腺瘤相关的压迫性视神经病变在临床上可能与青光眼性视神经病变难以区分。
病例报告
一名56岁男性，既往无重大病史，在6个月内视力迅速下降。眼底检查发现双侧不对称的青光眼样视盘凹陷。脑部MRI检查显示垂体肿瘤压迫视交叉。
结论
与垂体腺瘤相关的压迫性视神经病变的诊断可能很困难，因为它常常模拟慢性青光眼。然而，一些特征应提醒临床医生注意压迫性视神经病变的可能性，并促使进行神经影像学检查，以便获得早期诊断和治疗。
