ULTRASOUND FINDINGS of GIANT CELL TUMOR of the FEMUR, Dr LÊ THANH LIÊM, MEDIC MEDICAL CENTER, HCMC, VIETNAM



35yo male patient from Danang City suffered from his middle left thigh swelling for 6 months.


The result of histopathology was a giant cell tumor type II of the femur bone with 2 components= one, some giant cells with many nucleii and other, soft tissue with fibroblasts and histiocytes. There were a lot of macrocytes and hemorrhagic areas and hemosiderin accumulatings.



MSCT = Lesion at 1/3 middle of the left femur made lacking the intramarrow bone cliques , breaking the bone crust and infiltrating the soft tissue #7x8cm. There were calcifications into the bone marrow. In general the lesion image was like half tumor and half osteitis.












Ultrasound findings= Hypoechoic structure #10x3x3,6cm at 1/2 left thigh, hypervascular with osteonecrosis at anteriolateral of the femur and cystic formations with coarse fluid. There were 2 hypoechoic nodules 16 and 27 mm in the muscle and subcutaneous layer.












This was the first description of ultrasound findings of a giant cell tumor of the femur with trespassing on the soft tissue.
