| 目的 分析头颈部Kimura病的CT和MR表现。方法 收集经病理证实的Kimura病患者20例，分析其累及部位、边界、大小、数量、CT密度、MR信号特征。结果 20例患者中，19例为多发病变，累及腮腺11例，累及颌下区6例，颊部2例、硬腭1例，上臂2例，腋窝1例，1例单独累及下颈部淋巴结，8例伴有耳前耳后皮下结节，16例颈部淋巴结肿大，其中8例腮腺区淋巴结肿大。肿物最大径平均（3.09±1.08）cm，19例边界不清，1例边界清楚。CT平扫等密度16例，略低密度4例，均未发现钙化。CT增强扫描均匀强化16例，其中轻度强化4例，中等强化10例，明显强化2例，不均匀强化1例。MR扫描2例均表现为均匀信号，明显强化。结论 Kimura病CT和MR多表现为累及腮腺及皮下的多发病灶，伴多发颈部淋巴结增大且密度均匀，有助于诊断Kimura病。 |

| Objective To explore the CT and MRI manifestations of Kimura disease in head and neck. Methods The CT and MR findings of 20 cases with Kimura disease confirmed by pathology were collected. The lesion location, boundary, size, number, density of CT and signal intensity of MRI were analyzed. Results In 20 cases, multiple lesions were seen in 19 cases. There were 11 cases involving parotid gland, 6 cases involving the submandibular area, 2 cases in cheek, 1 case in palate, 2 cases involving the upper arm, 1 case involving axillary fossa, 1 case involving cervical lymph node alone, and 8 cases with subcutaneous nodules in the front or back of the ear, 16 cases accompanied by lymphadenopathy in the neck (8 cases with lymphadenopathy in the parotid gland). The largest diameter of lesion was (3.09±1.08)cm. The margin was blurred in 19 cases and well defined in 1 case. The isodensity lesions were found in 16 cases and slightly lower density lesions were in 4 cases in non-contrast enhanced CT scan. Calcification was not found in all cases. Homogeneous enhancement was found in 16 cases and inhomogeneous enhancement was found in 1 case. The enhancement degree varies from mild to strong enhancement. Homogenous signal and strong enhancement was found in 2 cases with MR scan. Conclusion The typical manifestations of Kimura disease are involvement of parotid gland and subcutaneous fat, accompanied by lymphadenopathy in the neck, homogeneous density on CT or MRI, which may indicate Kimura disease. |
