Purpose The aim of this study was to determine whether color Doppler or power Doppler sonography can aid in the diagnosis of hepatic cavernous hemangiomas. Methods We imaged 25 hepatic cavernous hemangiomas in 17 patients with gray‐scale, color Doppler, and power Doppler sonography. Five malignant lesions were also imaged in the same manner for reference. Hemangiomas had been previously diagnosed by biopsy in 8 patients (15 lesions) and by CT, MRI, and/or tagged red blood cell scanning in 9 patients (10 lesions). Results Of the 25 hemangiomas, color or power Doppler imaging showed no internal blood flow in 23. Of these 23 lesions, 11 showed a peripheral flow pattern believed to represent flow in displaced blood vessels. This pattern was better visualized with power Doppler imaging in 3 lesions and equally well visualized with color and power Doppler imaging in 8 lesions. Two hemangiomas that had unusual central fibrosis with large vessels in 1 patient showed diffusely increased blood flow on power Doppler study. All 5 malignant lesions showed flow in peripheral vessels, and 1 showed internal vascularity as well. Conclusions Neither color nor power Doppler imaging improved the capability of sonography for making a specific diagnosis of benign hepatic cavernous hemangioma. © 2000 John Wiley & Sons, Inc.
