Color Doppler sonographic findings in splenic hamartoma

We present the gray-scale and color Doppler sonographic findings in a case of a splenic hamartoma in a 40-year-old man. Gray-scale sonograms showed a 2 × 2 cm, hypoechoic splenic mass that was homogeneous without evidence of cystic change or calcification. Color Doppler sonograms showed multiple radial blood-flow signals inside the mass, and spectral analysis confirmed arterial and venous flow. Arteriograms showed multiple small, hypervascular masses with fine tumor vessels and tumor stains within the spleen. Histologic analysis following a splenectomy showed dilated vessels and congestion consistent with the color Doppler sonographic findings. © 2000 John Wiley & Sons, Inc.
