A case of a retained surgical sponge found in the retroperitoneum is presented with findings on magnetic resonance (MR) imaging, computed tomography (CT), ultrasonography (US) and angiography. Among all the performed modalities, a characteristic internal structure of the gauze granuloma was best visualized on MR imaging. If no radio-opaque marker is seen on plain radiography or CT, the folded fabric inner structure visualized on T2-weighted images can be a most important clue to the correct diagnosis of this iatrogenic mass.
本文报告了一例在腹膜后发现的遗留手术海绵病例，并展示了磁共振成像（MR）、计算机断层扫描（CT）、超声检查（US）和血管造影的检查结果。在所有已实施的检查方法中，纱布肉芽肿的特征性内部结构在MR成像上显示最佳。如果在X线平片或CT上未见不透射线标记物，T2加权图像上显示的折叠织物内部结构可能是正确诊断这种医源性肿块的最重要线索。
