【摘要】 目的 :提高超声对颈丛和臂丛神经鞘瘤诊断的准确性。方法 :应用 10 MHz高频彩色多普勒超声对经临床、手术及病理证实的 40例颈部椎旁间隙神经鞘瘤 (颈丛 12例 ,臂丛 2 8例 )与周围组织关系进行探查 ,从而准确解剖定位。结果 :颈丛和臂丛神经鞘瘤均位于椎旁间隙。颈丛神经鞘瘤位于颈动脉分叉水平及其上方 ,头长肌或前斜角肌后外方 ;而臂丛神经鞘瘤位于颈动脉分叉水平以下 ,紧贴前斜角肌后或后外方 ,颈横动脉横跨前斜角肌表面向肿瘤未被肌肉覆盖部分的浅面走行。结论 :通过彩色多普勒超声对颈丛和臂丛神经鞘瘤的准确解剖定位 ,可提高其对肿瘤诊断的准确性。更多还原

【Abstract】 Objective:To raise the accuracy of ultrasonic diagnosis for neurilemmoma of the cervical plexus and the brachial plexus.Methods:10 MHz high frequency color Doppler ultrasound was used to detect the paravertebral neurilemmoma of 40 patients,12 cases of which were from the cervical plexus,and others from the brachial plexus,All the cases were confirmed by clinical、surgical and pathological findings.The relationships between the tumors and their surrounding tissues were investigated,so as to get their accurate anatomic locations.Results:Both the neurilemmomas of the cervical and the brachial plexuses are in the paravertebral space.Neurilemmoma of the cervical plexus lies on or obove the carotid bifurcation,posterolateral to the longus capitis muscle or the anterior scalene muscle;while neurilemmoma of the brachial plexus lies below the carotid bifurcation,and posterior or posterolateral to the anterior scalene muscle.The transverse cervical artery which crosses the anterior scalene muscle covers the part of the tumor and lies superficially.Conclusions:Color Doppler ultrasound may raise the diagnostic accuracy for neurilemmoma of the cervical and the brachial plexuses by investigating their anatomic locations.更多还原
