ABSTRACT
PURPOSE:
Description of contrast-enhanced ultrasound (CEUS) patterns of hepatic lymphoma. MATERIALS ANDMETHODS:
Over a period of 6 years and 1 month from January 2006 to January 2012, nâ=â38 patients with histological or clinically apparent hepatic lymphoma were studied by means of CEUS prior to B-mode imaging.RESULTS:
Using B-mode imaging, lesions were hypoechoic in nâ=â37 (97.4â%) cases, while a focal lymphoma lesion was echo-rich in 1 case (2.6â%). For comparison, with CEUS, a hyperenhanced signal during the arterial phase was observed in nâ=â9 (23.7â%), an isoenhanced signal in nâ=â17 (44.7â%) and a hypoenhanced signal in nâ=â12 (31.6â%) cases. During the portal phase nâ=â2 (5.3â%) lesions were isoenhanced and nâ=â36 (94.7â%) were hypoenhanced followed by a hypoenhancement in nâ=â38 (100â%) cases in the late phase.CONCLUSION:
Lymphomas of the liver can cause different contrast accumulation in the arterial phase of CEUS.âFurthermore, a clear differentiation from other malignant liver lesions such as metastases is crucial as different contrast accumulation in the arterial phase of CEUS is observed. In the late phase, hepatic lymphomas lead to a hypoenhancement in CEUS, also known as a "wash-out" phenomenon. In conclusion, CEUS is helpful to differentiate hepatic lesions by means of evaluating the malignancy or benignancy. In this regard, the application of CEUS can help to find the right diagnosis. A final discrimination between malignant liver lesions, such as liver lymphomas, metastasis or HCC, remains impossible.
