Myxoid-round cell liposarcoma: MRI appearance after radiation therapy and relationship to response

Liposarcomas are classified into 4 different subtypes, with the myxoid-round cell variant demonstrating increased morbidity and metastatic potential dependent on cell composition. Unique to sarcomas, the myxoid-round cell liposarcoma is remarkably sensitive to radiation therapy in the pretreatment s...

Sumario:Liposarcomas are classified into 4 different subtypes, with the myxoid-round cell variant demonstrating increased morbidity and metastatic potential dependent on cell composition. Unique to sarcomas, the myxoid-round cell liposarcoma is remarkably sensitive to radiation therapy in the pretreatment setting, owing to the tumor morphology and vascular distribution. Herein we report a case of myxoid-round cell liposarcoma within the deep soft tissues of the thigh of an 81-year-old male with excellent neoadjuvant response to radiation. We briefly review treatment options.
