Abstract

We present two cases of skeletal metastases from myxoid liposarcoma, occurring several years after treatment of the primary tumors in the lower limb. The present two case reports have unusual radiological features only detectable by MR imaging and not by plain radiographs or bone scans. From the present two cases, we found that a negative plain radiograph of the spine or a negative bone scan could not exclude skeletal metastases from myxoid liposarcoma, and MRI was a more sensitive screening procedure for their detection, especially in T1-weighted images. Unusual radiological features of skeletal metastases from myxoid liposarcoma are not well documented and only a few cases have been previously reported. Our aim is to document two more patients exhibiting the unusual radiological features of skeletal metastases from myxoid liposarcoma to improve their early detection and management.
