摘　　要：目的探讨婴幼儿颈椎结核的高场MRI表现与临床分析。方法回顾性分析11例经临床抗结核治疗确诊的婴幼儿颈椎结核的高场强MRI表现。结果例婴幼儿颈椎结核病变5例累及颈6、7椎体,3例累及颈3-4椎体,2例累及颈4-5椎体,1例累及颈2-3椎体,3例椎管受累,6例椎旁冷脓肿形成。高场强MRI表现为2个相邻椎体T1WI低信号,T2WI高或混杂信号;椎旁冷脓肿边缘清楚,TlWI低信号,T2WI高或混杂信号;受累椎间盘消失或T2WI低信号。结论婴幼儿颈椎结核早期易延误诊断,易导致严重后凸畸形,是截瘫的危险因素,高场强MRI检查能显示病变,有助于其早期诊断。Objective To discuss high field MRI manifestations of the infant cervical tuberculosis and clinical analysis.MaterialsandMethods High field MRI features in 11 cervical tuberculosis patients proved by clinical anti-tuberculosis treatment were retrospectively analyzed.Results The lesion was located at the 6th and 7th cervical vertebra in 5 cases and at the 3rd and 4th cervical vertebra in 3 cases and at the 4th and 5th cervical vertebra in 2 cases and at the 2nd and 3rd cervical vertebra in 1 case. Canalis spinalis was involved in 3 of 11 cases, and paraspinal cold abscess in 6 cases. On high field MRI scans, the lesions were characterized by low or equal intensity signal on Tl weighted images and high or mixed intensity signal on T2 weighted images involving 2 adjacent vertebra. The boundary of paraspinal cold abscess was distinct with low intensity signal on Tl weighted images and high or mixed intensity signal on T2 weighted images. The intervertebral disc disappeared or appeared as low intensity signal on T2 weighted images. Conclusion High field MRI scanning can display the lesions of infant cervical tuberculosis and is helpful to early diagnosis of infant cervical tuberculosis.
