Ultrasonography of Neck Lymph Nodes in Children
在兒童頸部淋巴結診斷中應用超聲波檢查法

Abstract

Ultrasound is an ideal imaging tool for initial assessment of cervical lymph nodes in children. Grey scale ultrasound helps to evaluate the morphology of cervical nodes, whereas power Doppler ultrasound assesses the nodal vasculature. On grey scale ultrasound, useful sonographic features that help in identifying pathologic nodes include round contour, absence of echogenic hilus, intranodal necrosis, calcification, ill-defined borders, matting, and adjacent soft tissue oedema. On power Doppler ultrasound, evaluation of vascular pattern of lymph nodes helps to differentiate malignant and benign nodes. Ultrasound-guided fine-needle aspiration cytology is becoming popular in paediatric patients, and ultrasound-guided core biopsy is also possible in this group of patients under local anaesthesia. This article reviews these topics to provide an overview of ultrasonography of cervical lymphadenopathy in children.

對於兒童頸部淋巴結的早期評估來說,超聲波檢查是一種理想的影像診斷方法。灰階超聲可評估頸部淋巴結形態,多普勒超聲可評估結節的脈管系統。灰階超聲提供聲譜特徵從而幫助識別結節的病理特點,包括:輪廓、無淋巴門回聲、結節內壞死、鈣化、欠清晰的邊界以及周圍組織水腫。多普勒超聲評估淋巴結血管結構,有助於鑒別惡性以及良性的淋巴結。當前,超聲引導下的細針穿刺細胞學越來越多地應用到兒科病人中。而超聲引導下粗針穿刺則用於需局部麻醉病人中。本文針對以上內容進行綜述,回顧超聲檢查法在兒童頸部淋巴結病中的應用。
