Clinical Summary

A 65 Y/O woman with wrist pain

 

 

Imaging Procedures and Findings

There is fluid around ext.carpi ulnaris tendon which suggest tearing of this tendon. Abnormal signal intensity in ulnalunate, ulnatriquetral ligament and TFC cartilage is suggestive of injury and partial tear of these components that called TFCC tear.

 

Discussion

The TFCC is a segment of cartilage in the wrist joint. The TFCC is considered the 'wrist meniscus,' because it functions very similar to the knee meniscus. The TFCC is also prone to cartilage tears that can cause symptoms of wrist pain and clicking or catching sensations. An articular disc was considered to be normal if images revealed uniformly low signal intensity at both the radial and the ulnar Findings suggestive TFCC tear including radial or ulnar avulsion or detachment; complete or partial perforation of the mid-substance of the articular disc; degenerative intrasubstance changes, as manifested by increased signal intensity and loss of the normal contour of the articular disc; and joint fluid coursing through a defect in the articular disc. Complete tears were defined as full-thickness foci of discontinuity that extended from the radiocarpal side of the articular disc to the distal radio-ulnar side. Partial tears were defined as foci of abnormal morphology and increased signal intensity that did not extend all the way from one side of the articular disc to the other.

 

Final Diagnosis

Traumatic TFCC tear
