摘要
目的：探讨木村病的MR及CT表现。方法：回顾性分析经手术病理证实的10例腮腺区木村病的影像表现，其中8例行MRI检查，2例行CT检查，1例为术后复发，9例为初诊。结果：男性8例，女性2例，年龄35～62岁，肿块均位于耳前腮腺区，部分肿块较大可达颞部皮下，最大截面达8cm×2．5cm，最小为2．6cm×2．2cm。均伴有局部淋巴结肿大，MR平扫一般T1WI呈等低信号，T2WI呈高低混杂信号，增强后均见明显强化。CT平扫病灶区密度较正常腮腺高。结论：腮腺木村病的影像有一定的特征性，对于腮腺区无痛性肿块并伴有局部淋巴结肿大的患者，尤其伴有外周血嗜酸性粒细胞及血清IgE升高者，应考虑木村病的可能。
Purpose： To study MR and CT manifestations of Kimura disease. Methods： Imaging features of 10 Kimura diseases of parotid area which were pathologically proven were retrospectively analyed. Of these patients, 8 cases underwent MRI, 2 cases underwent CT, 1 case was recurrence after surgery, 9 cases were newly diagnosed. Results： The patients included 8 males, 2 females, aged 35 - 62 years old. Masses were located in the parotid gland area behind the ear, part of the larger masses reached to temporal skin, the largest cross - section area was 8.3cm ×2.5cm, the minimum was 2.6cm ×2.2cm. All masses accompanied with local enlarged lymph nodes. MR scans showed iso - low signal on TlWI, mixed high and low signal on T2WI , apparently enhancement after enhanced. Lesions showed higher density than the normal parotid glands on CT scans. Conclusion： The images of parotid gland Kimura disease has some characteristics, patients with painless mass in the parotid region and accompanied with local enlarged lymph nodes, particularly associated with elevated peripheral blood eosinophils and serum IgE, should be considered Kimura disease possible.
