Purpose: We investigated the difference in injury of the corticospinal tract (CST) and the spinothalamic tract (STT) in patients with pu­taminal hemorrhage, using diffusion tensor tractography (DTT).Methods: Thirty one consecutive patients with PH and 34 control subjects were recruited for this study. DTT scanning was performed at early stage of PH (7-63 days), and the CST and STT were reconstructed using the Functional Magnetic Resonance Imaging of Brain (FM­RIB) Software Library program. Injury of the CST and STT was defined in terms of the configuration or abnormal DTT parameters was more than 2 standard deviations lower than that of normal control subjects.Results: Among 31 patients, all 31 patients (100%) had injury of the CTS, whereas 25 patients (80.6%) had injury of the STT: the inci­dence of CST injury was significantly higher than that of STT (p<0.05). In detail, 20 (64.5%) of 31 patients showed a discontinuation of the CST in the affected hemisphere; in contrast, 14 patients (45.2%) of 31 patients showed a discontinuation of the STT in the affected hemisphere. Regarding the FA value, 6 (19.4%) of 31 patients and 2 (6.4%) of 31 patients were found to have injury in the CST and STT, respectively. In terms of the fiber number, the same injury incidence was observed in 11 patients (35.5%) in both the CST and STT.Conclusion: The greater vulnerability of the CST appears to be ascribed to the anatomical characteristics; the CST is located anteriorly to the center of the putamen compared with the STT.
