Study Design: Case report.
Objective: To report a rare case of alkaptonuria presenting as a T1-hyperintense disc herniation.
Summary Of Background Data: 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.
Methods: A single patient is reported.
Results: Pathologically proven patient presentation with radiological and pathological images.
Conclusion: We report a rare case of alkaptonuria presenting as a T1-hyperintense disc herniation.

Objective: To investigate the relationship between condylar marrow signal abnormalities and temporomandibular joint internal derangement (TMJID).
Methods: Oblique sagittal T1 weighted MR imaging at closed and open mouth and Oblique sagittal T2 weighted MR imaging at closed mouth were obtained from 88 joints of 44 patients suffering from TMD. Condylar marrow signal abnormalities were reviewed and classified into bone marrow edema pattern (hypointense T1, hyperintense T2), sclerosis pattern (hypointense T1 and hypointense T2) and combined edema and sclerosis pattern.
