Most recent modalities for diagnosing hepatic tumors are based on evaluation of the arterial and portal flow of the tumors. However, pseudo-lesions resulting from A-P shunting, and aberrant circulation of splancnic veins may occur, which often make it difficult to reach a definitive diagnosis. Real-time virtual ultrasonography, however, presents a virtual cross-section reconstructed from CT data. This modality has proven to be very useful for the detection of lesions which are difficult to find with the usual methods. With this modality, we could identify a pseudo-lesion co-existing with HCC from an actual tumor. The dignosis was based on both the image showing the continuation of the lesion to the cyctic wall and the results of a histological examination performed with reference to the virtual US image.
