[Giant haemangioma of the liver - clinical and diagnostic problems - a case report]

Typical echodense haemangiomas of the liver can easily be identified by B-scan ultrasound. Atypical or giant haemangiomas of the liver, however, need to be differentiated from secondary tumours or primary liver carcinomas and cholangiocarcinomas. Until recently, computed tomography or magnetic resonance tomography were required to confirm the diagnosis, and not so rarely even a fairly risky fine-needle puncture had to be performed. Contrast media-assisted sonography, in general, offers the same scope of differentiating liver tumours as the radiographic tomography methods. Contrast media-assisted sonography is not yet widely available and has not been sufficiently evaluated. One important limitation is thought to be the lack of echo depth. We demonstrate the diagnostic value of this method in the case of a liver haemangioma measuring more than 20 cm in diameter. The resulting clinical questions are being discussed.
