目的分析双肾与胰腺慢性肉芽肿的MRI表现,以提高对该病的认识水平。资料与方法对1例经手术病理证实的双肾与胰腺慢性肉芽肿MRI表现包括形态、信号及强化特点进行观察,结合临床资料与其他影像学资料进行分析。MRI检查采用梯度回波T1WI、快速自旋回波T2WI平扫、梯度回波T1WI动态增强扫描。结果双肾为多发局灶性病变,部分见囊变区。胰腺弥漫性肿大。均呈长T1、稍短T2信号。增强扫描动脉期无明显强化,静脉期及延时期逐渐强化。结论通过对双肾与胰腺慢性肉芽肿的MRI表现分析,结合临床资料与其他影像学表现,可加深对腹腔脏器肉芽肿性病变的认识并与肿瘤性病变进行鉴别。
Objective To analyze MRI manifestations of chronic granuloma in both kidneys and pancreas in order to improve their understanding of the disease. Materials and Methods MRI findings of 1 case of chronic granuloma of the kidney and pancreas confirmed by surgery and pathology were observed including morphology, signal and enhancement features. The clinical data and other imaging data were analyzed. MRI examination using gradient echo T1WI, fast spin echo T2WI plain scan, gradient echo T1WI dynamic contrast-enhanced scan. Results Kidney for multiple focal lesions, some see cystic area. Pancreatic diffuse enlargement. Showed long T1, slightly shorter T2 signal. Enhanced scanning arterial phase no significant enhancement, venous phase and delayed phase gradually strengthened. Conclusion MRI findings of chronic granuloma in both kidneys and the pancreas can be combined with clinical data and other imaging findings to deepen the understanding of granulomatous lesions of abdominal organs and differentiate them from neoplastic lesions.
