We report on a patient with mild traumatic brain injury (TBI) by follow-up diffusion tensor tractography (DTT), and observed for approximately nine monthsby serial diffusion tensor tractography (DTT).
A 66-year-old male patient was injured in a car crash. Approximately four weeks after the crash, he developed a tremor in the right hand and leg. His symptoms worsened over time.
Approximately six months after the crash, he developed a mild tremor in the left hand. Nine months after the crash, he manifested severe tremor in his right hand, mild resting and intentional tremor in his left hand and both legs, and mild trunkal ataxia.
N/A.
On 3-week DTT, well reconstructed DRTTs were observed in both hemispheres, except for the thinned lower portion of the right DRTT. On 9-month DTT, the right lower DRTT had thinned compared with the 3-week DTT and showed a disruption at the upper portion. The left DRTT showed thinning in the lower portion and tearing in the upper portion compared with 3-week DTT.
Aggravation of an injured DRTT was demonstrated in a patient with mild TBI, using serial DTT examination.
我们通过随访扩散张量纤维束成像（DTT）报告了一名轻度创伤性脑损伤（TBI）患者，并通过系列扩散张量纤维束成像（DTT）观察了约九个月。
一名66岁男性患者在车祸中受伤。车祸后约四周，他右手和右腿出现震颤，症状随时间加重。
车祸后约六个月，他左手出现轻度震颤。车祸后九个月，他右手出现严重震颤，左手和双腿出现轻度静止性和意向性震颤，以及轻度躯干共济失调。
无。
在3周的DTT检查中，除右侧DRTT下部变薄外，双侧半球的DRTT均重建良好。在9个月的DTT检查中，与3周时相比，右侧DRTT下部变薄，上部出现中断。与3周时相比，左侧DRTT下部变薄，上部撕裂。
通过系列DTT检查，在一名轻度TBI患者中证实了受伤的DRTT会加重。
