Farbcodierte Dopplersonographie (FD-Sonographie) primärer und sekundärer Lebertumoren

A 3-cm lesion indicative of focal nodular hyperplasia (FNH) of the liver was coincidentally detected in a 21-year-old female. Ultrasonography (US), computed tomography (CT), magnetic resonance (MR) imaging and liver scintigraphy all proved nonspecific. However, color Doppler US demonstrated characteristic vascular patterns of FNH of the liver, including (a) hypervascularity of the mass, (b) an enlarged afferent blood vessel in the tumor with blood flow toward the center of the tumor, and (c) arterial pulse waves in all the vessels in the lesion, detected by means of the fast Fourier transformation (FFT). With selective hepatic angiography, a "spoke-wheel" pattern was revealed. The angiographic pattern corresponded well to that shown by color Doppler US. On the basis of the findings from these two modalities, the diagnosis of FNH was made. This report examines the effectiveness of color Doppler US in the differential diagnosis of FNH, compared with other imaging modalities.

During the past decade, the diagnostic technologies concerning the hepatocellular carcinoma have been enriched by the vascular doppler ultrasound, the ultrasound echo-enhancing agents and the magnetic resonance tomography. The therapeutic possibilities have been augmented by the percutaneous ethanol instillation therapy, the combination of local therapies with transcatheter arterial embolisation and the more effective after-treatment after transplantation and segment resection. The use of the respective treatment modalities depends on the tumor constellation, the functional liver reserve, the patients general condition and the risk/benefit ratio of the treatment. The quality of life should be optimized because of the poor tumor prognosis. As there have been no real advances in the treatment of hepatocellular carcinoma to date, the prevention and early diagnosis of the tumor in high risk populations is of utmost importance.
