Imaging of vascular soft tissue tumors.

ABSTRACT

Most tumors of the vascular system are benign, cutaneous or subcutaneous lesions that are usually readily diagnosed without significant differential diagnosis. On the other hand, lesions that arise in deep soft tissues have to be differentiated from malignant neoplasms. In these cases, further imaging work-up is necessary for local staging and planning therapy. Vascular lesions of intermediate malignancy and malignant vascular tumors are very rare and demonstrate nonspecific imaging findings. This manuscript aims to give a brief overview of vascular soft-tissue tumors and to discuss the imaging appearances.
