We report a case of extravasation of an antitumor agent by preoperative magnetic resonance (MR) imaging. MR studies demonstrated a decreased signal intensity on T1- and T2-weighted images and a strong enhancement of contrast media in injured tissue, including subcutaneous adipose tissue and deep fascia, which was cicatrical macroscopically. The MR findings were in good agreement with the macroscopic findings. We believe that MR imaging is useful for estimating deep tissue damage due to extravasation of an antitumor agent.
我们报告一例通过术前磁共振成像（MR）发现的抗肿瘤药物外渗病例。MR研究显示，在T1加权和T2加权图像上信号强度降低，包括皮下脂肪组织和深筋膜在内的损伤组织中造影剂有强烈增强，肉眼可见为瘢痕组织。MR表现与肉眼所见高度一致。我们认为，MR成像有助于评估抗肿瘤药物外渗所致的深部组织损伤。
