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.MethodsA single patient is reported.ResultsPathologically proven patient presentation with radiological and pathological images.ConclusionWe report a rare case of alkaptonuria presenting as a T1-hyperintense disc herniation.
