Case report.
To report a rare case of alkaptonuria presenting as a T1-hyperintense disc herniation.
A 46-year-old man without previous diagnosis of alkaptonuria underwent evaluation for progressive back pain revealing a T1-hyperintense disc herniation at the L3-L4 level. Discectomy recovered a blackened disc that was pathologically confirmed to be nucleus pulposus with alkaptonuric involvement. The differential diagnosis of a T1-hyperintense, T2-hypointense disc on magnetic resonance imaging is discussed, with emphasis on the pathophysiology of alkaptonuria.
A single patient is reported.

病例报告。
报告一例罕见的尿黑酸尿症表现为 T1 高信号椎间盘突出症的病例。
一名 46 岁男性,无尿黑酸尿症既往诊断,因进行性腰痛接受评估,显示 L3-L4 水平 T1 高信号椎间盘突出症。椎间盘切除术恢复了一个变黑的椎间盘,病理证实为伴有尿黑酸尿症的髓核。讨论了磁共振成像上 T1 高信号、T2 低信号椎间盘的鉴别诊断,重点介绍了尿黑酸尿症的病理生理学。
