Transverse color and spectral US of the palpable lesion (above left) shows a discrete well circumscribed soft tissue mass with markedly increased vascularity. Axial T1 MRI without contrast of the spine (below left) shows the palpable mass to be in the subcutaneous tissues and to have low signal intensity, while on the axial T2 MRI (above right) the mass has high signal intensity. Axial T1 MRI with contrast and fat supression (below right) shows the mass to enhance markedly and uniformly.
