| Objective To investigate the reason and clinical symptoms of the abnormally rotated brainstem by 3.0T MRI. Methods Clinical, conventional MRI, and MRA datas were collected from 103 consecutive patients with abnormality rotated brainstem on MRI between October 2006 and August 2007. The appearance of MRI, the course of vertebro-basilar artery, the degree of the rotated brainstem, and the dilation of the ventricular system were recorded. The results were analyzed statistically. Results There is no abnormally rotated brainstem in the control group. The number of the abnormally rotated medulla oblongata is more than abnormally rotated pons. Whether the vertebral artery acrossing the median line had close relationship with the abnormally rotated brainstem (χ2＝51.709,P＝0.000, correlation coefficient r=0.98), the diameter of the vertebral artery had close relationship with the abnormally rotated brainstem (χ2＝22.117,P＝0.000, correlation coe fficient r=0.93). The larger the degree of the abnormally rotated brainstem, the heavier the clinical symptoms, and the more complicated clinical symptoms. Conclusion Tortuose and coarse vertebro-basilar artery is one of the most important reasons of the rotated brainstem, and the abnormally rotated brainstem may provoke some brain symptoms. |
