Vascular bone tumors of the pelvis and extremities: an 18-case clinical and radiological analysis

In vascular bone tumors of the pelvis and extremities, the presence of a soft tissue component and tumor size ≥ 5.5 cm are among the most useful radiological features associated with malignancy. While benign lesions generally have excellent outcomes with curettage, malignant tumors are associated with a poor prognosis. Histopathological confirmation remains essential, and larger series are needed to refine diagnostic and prognostic criteria.
