Abstract


Objectives: We investigated injury of corticostriatal (CStr) tract in patient with mild traumatic brain injury (mTBI), which was demonstrated by DTT.

Method: A 44-year-old female with no previous history of neurological, physical, or psychiatric illness had suffered from head trauma resulting from a pedestrian car accident. She complained that could not quickly move the left hand with her intension. After three month’s administration, her slowness movement of left hand recovered rapidly to the point that she was able to extend all fingers quickly.

Results: On DTT configuration, the integrity of the left CStr tract was well-preserved, however the right CStr tract showed narrowing and partial tearing in the subcortical white matter on a DTT at 25 months after onset.

Conclusion: Injury of the right CStr tract was demonstrated in a patient who developed mild motor control problems following mild TBI. We believe that the evaluation of the CStr tract from the secondary motor area for patients who showed unexplained motor control problem is necessary.
