Tuberculosis in the neck;Key Words;Key Words;Introduction;简介;Imaging findings CT and MRI findings in the acute stage include diffuse bilateral glottic thickening, with or without an associated mass。The commonest finding in the chronic stage is a localized lesion granuloma mimicking a mass. ;影像表现;Fig 1 Axial CECT of the larynx shows a large, enhancing, tumour like granulomatous mass in pre-epiglottic space (black arrow) with caseating right cervical lymph node (white arrow).;图1、喉部轴位CT图像显示，会厌前间隙可见体积较大、明显强化、类似肿瘤的肉芽肿肿块(黑色箭头)和右颈部干酪样坏死淋巴结(白色箭头)。 ;Thyroid;甲状腺;Imaging findings CT demonstrate multiple, small, focal lesions in the entire gland resembling miliary TB (Fig. 7). Caseating granulomas can cause enlargement of the gland with cold abscess formation with or without sinus formation. ;影像表现;Figure.2 Axial image of the thyroid gland. Miliary low density nodules (open arrows) in the entire thyroid gland.;图2、甲状腺轴位图像显示在整个甲状腺中多发粟粒状的低密度结节影(空心箭头)。;Neck abscess;颈部脓肿;;影像表现;Figure 3、Coronal CT image of the neck showing a large, peripherally enhancing, centrally liquefied, multiseptate, transpatial cold abscess (white arrows) with airway (white arrowheads) and vascular mass effect.; 图3、颈部冠位CT示：体积较大、周边强化、中心液化坏死、跨间隙生长的冷脓肿，伴气道(白色箭头)和血管(白色箭头)的占位效应。;Conclusion;结论;
