| 目的 探讨MRI在局灶性巨大淋巴结增生症诊断中的应用价值。方法 回顾性分析经病理证实的6例局灶性巨大淋巴结增生症患者的MRI表现。结果 本组6例巨大淋巴结增生症患者中包括颌颈部病变4例,腹部病变2例,均为透明血管型,形态为圆形或卵圆形,边缘较光滑,MRI平扫表现为等或稍长T1、稍长T2信号影,信号匀匀,未见明显坏死或钙化,动态增强扫描所得时间信号强度曲线表现为速升缓降或平台型,DWI序列呈均匀的弥散受限高信号,其ADC值为(1.02±0.23)×10-3mm2/s。结论 局灶性巨大淋巴结增生症的MRI表现具有特征性,常规MRI结合DWI序列及动态增强扫描有更高的诊断价值。 |

| Objective To analyze the value of MRI in the diagnosis of focal Castleman's disease.Methods Six cases of pathologically-proved focal Castleman's disease were retrospectively analyzed.Results The lesions that located in the neck were 2 cases, and in the abdomen 4 cases. All of them were hyaline vascular type. The well-circumscribed lesions were round or oval. The lesions exhibited iso-intensity or hypo-intensity signal on T1-weighted images and hyperintensity signal on T2-weighted images. None of 6 lesions had necrosis or calcification. The patterns of time-signal intensity curve of dynamic contrast-enhanced MRI in 6 patients considered to have early enhancement and low washout. The average ADC value at the region with most significantly restricted diffusion was (1.02±0.23)×10-3mm2/s.Conclusion MRI manifestations of focal Castleman's disease have certain imaging characteristics, and conventional MRI combined with DWI and dynamic enhanced scanning has higher diagnostic value. |
