Abstract

Diffuse, asymptomatic skeletal metastases occurred in a 46-year-old patient with liposarcoma. These metastases were detected by magnetic resonance imaging (MRI) but not by roentgenograms or radionuclide scans. Pathologic confirmation from the MRI-detected area was obtained. This observation suggests a possible explanation for the present discrepancy between the incidence of skeletal involvement in antemortem and postmortem studies in metastatic liposarcoma. MRI may be an extremely sensitive tool for detection of bone and bone marrow metastasis.

摘要

一名46岁的脂肪肉瘤患者出现了弥漫性、无症状的骨骼转移。这些转移灶通过磁共振成像（MRI）检测到，但X线片或放射性核素扫描未检测到。从MRI检测区域获得了病理证实。这一观察结果为目前转移性脂肪肉瘤生前和死后研究中骨骼受累发生率之间的差异提供了一种可能的解释。MRI可能是检测骨骼和骨髓转移的极其敏感的工具。
