The diagnosis of a retained surgical sponge was made by CT and sonography in four patients. The plain abdominal radiograph was normal in all cases. In each of four cases of gauze granuloma, CT showed a well-defined round mass with a thick wall; internal heterogeneous densities with a wavy, striped, and/or spotted appearance; mottled calcifications; and gas bubbles. Sonography disclosed a well-defined hypoechoic mass containing highly echogenic foci with a strong posterior shadow. In these cases, CT and sonographic findings, together with a history of surgery, permitted the correct preoperative diagnosis of a retained foreign body.
4例患者通过CT和超声检查诊断为手术中遗留手术海绵。所有病例的腹部平片均正常。在4例纱布肉芽肿病例中，CT显示边界清晰的圆形肿块，壁增厚；内部密度不均匀，呈波浪状、条纹状和/或斑点状；有斑点状钙化；还有气泡。超声检查发现一个边界清晰的低回声肿块，内有高回声灶，并伴有明显的后方声影。在这些病例中，CT和超声检查结果，结合手术史，使得术前能够正确诊断出异物残留。
