Liposarcoma is one of the most common soft tissue sarcomas, representing 9-18 % of all cases. Most often the diagnosis is determined by CT or MRI, and differentiation from lipoma is not always easy. Unlike other types, myxoid liposarcomas have an unusual tendency to produce extrapulmonary metastases, mainly in the bones and soft tissues. For determing the diagnosis in this case we used a multimodal approach involving several imaging studies – three phase and whole body bone scintigraphy, hybrid imaging methods (SPECT/CT, PET/CT) and magnetic resonance imaging (MRI). Our observations suggest that the separate use of the applied imaging methods was not sufficient for the diagnosis, but the combined functional-morphological approach was the most pathognomonic. This approach with a single study provides a complex information, which leads to a fast therapeutic decision.
