手术创伤引起的对比度增强可能模仿残留强化的肿瘤，从而使术后计算机断层扫描的解释复杂化。我们评估了10例脑肿瘤患者术后增强的自然病史。对比增强不同于残留强化的肿瘤，可见于肿瘤切除后的手术边缘，而不是肺叶切除。强化最早出现在术后第五天，两周时最为强烈，并持续了几个月。术后第5天前，增强扫描显示肿瘤残留。肿胀和伪影在术后第1天和第2天比第3天和第4天更明显。我们建议在术后第三天或第四天进行计算机断层扫描以评估残留的强化肿瘤。这一时机避免了术后增强，并最大限度地减少了伪影造成的解释困难。
Contrast enhancement resulting from surgical trauma may mimic residual enhancing tumour, thereby complicating the interpretation of postoperative computed tomographic scans. We assessed the natural history of postoperative enhancement in 10 patients with brain tumour. Contrast enhancement distinguishable from residual enhancing tumor appered along the operative margin followingtumor resections but not lobectomies. Enhancement appeared as early as the fifth postoperative day, was most intense at two weeks, and persisted for several months. Prior to the fifth postoperative day, enhancement reflected residual tumor. Edema and artifacts were more prominent on the first and second postoperativedays than on the third and fourth. We recommend that postoperaive computed tomographic scans to assess residual enhancing tumor be performed on the third or fourth postoperative day. This timing avoids postoperative enhancement and minimizes interpretative difficulties caused by artifacts.
