【摘要】：目的探讨头颈部木村病的临床及MRI表现,以提高对本病的认识。方法对11例经手术或活检病理证实的头颈部木村病患者的临床特征及MRI表现进行回顾性分析。结果木村病多发生于中青年男性,好发于头颈部皮下,常累及大涎腺,T_1WI呈等或稍高信号,T_2WI呈高信号,且病灶内常伴流空信号及条索样低信号,增强后明显渐进性强化,多伴有腮腺周围、颌下及颈部淋巴结肿大。病灶周围常见皮肤增厚,皮下脂肪萎缩。结论木村病的MRI表现具有一定特点,结合临床表现和实验室检查,可明显提高术前诊断的准确率。
[Abstract]:Objective to investigate the clinical and MRI manifestations of head and neck Kimura disease. Methods the clinical features and MRI findings of 11 patients with head and neck Kimura disease confirmed by operation or biopsy were analyzed retrospectively. The lesions often involve the large salivary gland on T _ 1WI with iso-or slightly high signal intensity and high signal intensity on T _ 2WI, and the lesions are often accompanied by emptying signal and strip-like low signal intensity. After enhancement, the enhancement is obviously gradual, and most of them are accompanied by parotid gland circumference. Submaxillary and cervical lymph nodes were enlarged. Skin thickening and subcutaneous fat atrophy were common around the lesions. Conclusion the MRI findings of Kimura disease have some characteristics. Combined with clinical manifestations and laboratory examination, the accuracy of preoperative diagnosis can be improved significantly.
