In musculoskeletal (MSK) ultrasound, soft tissue sarcoma (STS) often presents as a heterogeneous, solid mass with irregular margins and internal vascularity, crucial for diagnostic imaging. These malignant tumors, originating from connective tissues, may show areas of necrosis or cystic degeneration, impacting their echotexture. Early detection via ultrasound is vital for accurate medical diagnosis and staging, guiding subsequent biopsy and treatment.
Ultrasound findings for STS include rapid growth, invasion into surrounding tissues, and potential calcifications. Color Doppler typically reveals increased blood flow within the lesion, a key indicator for differentiating benign from malignant masses. Mastering these ultrasound characteristics is essential for sonographers and radiologists to improve diagnostic precision in medical oncology.
