Soft-tissue tumors provide a significant part of a pediatric radiologists’ work. Using the World Health Organization (WHO) soft-tissue tumor classification system, those most relevant to pediatric imaging can be broadly categorized into tumors of adipocytic, fibroblastic/myofibroblastic, so-called fibrohistiocytic, vascular, nerve sheath, uncertain differentiation, smooth and skeletal muscle origin. Ultrasound remains the primary modality of choice as it is quick, provides excellent soft-tissue resolution, allows assessment of vascularity, is cost-effective and does not require sedation in young children. With rapidly advancing technology, exquisite soft-tissue detail can now be achieved, and along with additional knowledge of the natural history and imaging characteristics of soft-tissue tumors in recent years, the diagnostic accuracy of US has significantly increased. The objectives of this exhibit are to review the sonographic imaging findings of benign and malignant pediatric soft-tissue tumors and present specific features that aid diagnosis using illustrative examples from our institutions.
