Background: liposarcoma is a malignant tumor of soft tissue and the most common sarcoma in the adult life. The myxoid liposarcoma accounts for 30 to 35 % of all liposarcomas. It is commonly seen on the thighs. Only two cases in which the liposarcoma was found in the vertebral column have been reported. Clinical case: this is a 28 year old woman with symptoms of spinal cord injury by compression (tottering gait, weakness 4/5 and decreased sensibility in right leg). The MRI showed a right paravertebral multinodular mass from L4 to S2, with solid and cystic aspects, following the S1 and S2 intervertebral foramen to the presacral space, with low signal intensity on T1 and high on T2. The diagnosis of neurofibroma was concluded. The patient was scheduled for surgery. Extra and intraspinal excision was performed and a mass was removed. Histopathologic study reported myxoid liposarcoma. Conclusions: liposarcoma is a malignant tumor of soft tissues. The spine is a rare location for this neoplasm, even for metastases. It is difficult to achieve a complete resection in this localization, so the recurrence rate is high.
