To define the role of computed tomography (CT) in identifying and classifying the imaging patterns of diagnostic value in Kimura's disease of the head and neck.
A retrospective study was undertaken comprising 13 patients with histopathological evidence of Kimura's disease. The patients' clinical and pathological records were reviewed against a detailed analysis of their CT images performed from the base of the skull to the arch of the aorta.
Both well-defined, nodular masses, as well as ill-defined plaque-like infiltrative masses were seen in the subcutaneous tissue of the head and neck region. All patients had lesions adjacent to the major salivary glands. The parotid gland was affected in 10 of the 13 cases and the submandibular gland was affected in the rest. Contrast enhancement was variable. More than half of the cases had associated lymphadenopathy. Some of them showed atrophy of the skin and subcutaneous fat overlying the subcutaneous masses. Blood eosinophilia was a consistent feature in all the cases.
The patterns of distribution, morphology, and enhancement of the lesions in Kimura's disease that can be demonstrated at CT, enables a confident, non-invasive diagnosis of this condition, in an appropriate clinical context.
明确计算机断层扫描（CT）在识别和分类头颈部木村病具有诊断价值的影像学表现中的作用。
进行一项回顾性研究，纳入13例有木村病组织病理学证据的患者。对照从颅底至主动脉弓对其CT图像进行的详细分析，回顾患者的临床和病理记录。
在头颈部区域的皮下组织中可见边界清晰的结节状肿块以及边界不清的斑块状浸润性肿块。所有患者均有病变毗邻主要涎腺。13例中有10例腮腺受累，其余病例下颌下腺受累。对比增强情况各异。超过半数病例伴有淋巴结病。其中一些病例显示皮下肿块上方的皮肤和皮下脂肪萎缩。血液嗜酸性粒细胞增多是所有病例的一个一致特征。
CT上可显示的木村病病变的分布、形态和强化模式，在适当的临床背景下能够对该病进行可靠的非侵入性诊断。
