The magnetic resonance images show a large soft tissue mass extending into the popliteal fossa.
As with all sarcomata, MRI is the imaging procedure of choice because of its excellent tissue contrast and ability to depict the lesion in multiple planes. MRI is useful for evaluating the extent of the tumor and its involvement of adjacent soft-tissue structures. For instance, MRI is helpful in the differentiation of tumor from muscle tissue and in depicting the involvement of neurovascular structures, tendons, fascial/fat planes, and bone marrow. MRI is also helpful for the differentiation of recurrent soft-tissue tumors from postsurgical or postirradiation changes.
Chemotherapy and as the tumour encased the neurovascular bundle and was not resectable, an above knee amputation was done.
