To investigate corticospinal tract (CST) status using diffusion tensor imaging (DTI) in patients who had clinical symptom of torticollis but no definite cause of sustained symptom of torticollis. We evaluated 10 patients with sustained torticollis and 12 age-matched control subjects. All patients showed no specific fibromatosis coli findings on neck sonography. Even after intensive manual therapy, there was no improvement of clinical symptom of torticollis. DTI was performed using 1.5 T with a synergy-L Sensitivity Encoding (SENSE) head coil. Fractional anisotropy and apparent diffusion coefficient were measured using the region of interest method, and diffusion tensor tractography was conducted. We estimated the asymmetric anisotropic index (AA) and asymmetric mean diffusivity index (AD) to evaluate the asymmetry between right and left CSTs. All patients showed only torticollis symptom but no definite hemiplegic pattern on their extremities at initial evaluation. DTT, which was performed to reveal the reason of sustained asymmetric postural symptom showed hemiplegic pattern. The results of DTT corresponded to the delayed hemiplegic symptoms, which were found in the patients at second evaluation. AA and AD values between patients and control group were significantly different. Torticollis is usually caused by fibromatosis coli, but may be one of the symptoms of hemiplegia. DTI may be an additional technique for the early detection of hemiplegia in patients with sustained symptoms of unexplainable postural torticollis.

Most of the motor recovery in stroke occurs within 3 months after stroke onset and this period has been regarded as critical for motor recovery. Little is known about the motor recovery process during the critical period of stroke. We report on a patient with intracerebral hemorrhage (ICH) who showed recovery of an injured corticospinal tract (CST) during the critical period for motor recovery. A 43-year-old woman underwent conservative management for a spontaneous ICH in the right corona radiata and basal ganglia. She presented with complete left hemiplegia at the onset of ICH. She showed continuous and slow recovery, and consequently, she was able to flex her left fingers without gravity at 6 weeks after onset and extend the left fingers without gravity at 12 weeks. The 3- and 6-week DTTs showed that the right CST was discontinued around the hematoma. However, the 12-week DTT revealed that the right CST was originated from the right primary motor cortex and descended along the CST pathway. No motor evoked potential (MEP) was evoked from the right hemisphere on the 3- and 6-week TMS study. However, on the 12-week TMS study, an MEP which had the characteristics of the CST was evoked from the right hemisphere to the left abductor pollicis brevis muscle. Our results indicate that the injured right CST had been recovered between 6 weeks and 12 weeks after ICH onset. Consequently, we believe that this case demonstrated the recovery process of a severely injured CST during the critical period for motor recovery after ICH.
