客观的。低度恶性粘液纤维肉瘤在手术切除后经常反复复发，具有不寻常的浸润性生长模式，有时在病理检查时没有离散的肿瘤结节。本研究旨在通过 CT 和 MRI 确定并显示低度恶性粘液纤维肉瘤的复发模式。结论。与大多数其他组织学类型的低级别软组织肉瘤不同，复发性低级别粘液纤维肉瘤通常是浸润性的。显示出逐渐变细、尾状边缘和表面展开的构造；并转移至各个远处部位，包括肺、胸膜、骨、肾上腺、软组织和肠系膜。了解这些不寻常的特征对于在手术再切除前评估复发性低度粘液纤维肉瘤的存在和程度非常重要。
OBJECTIVE. Low-grade myxofibrosarcoma often relentlessly recurs after surgical resection, with an unusual infiltrative growth pattern and sometimes without a discrete tumor nodule at pathologic examination. This study was undertaken to determine and show patterns of recurrent low-grade myxofibrosarcoma at CT and MRI.CONCLUSION. Unlike in most other histologic types of low-grade soft-tissue sarcoma, recurrent low-grade myxofibrosarcoma often is infiltrative; shows a tapering, tail-like margin and superficial spreading configuration; and metastasizes to various distant sites, including lungs, pleura, bone, adrenal gland, soft tissue, and mesentery. Knowledge of these unusual characteristics is important in assessing the presence and extent of recurrent low-grade myxofibrosarcoma before surgical reexcision.
