Fig. 9From: The imaging conundrum of hepatic lymphoma revisitedSecondary anaplastic large cell lymphoma of liver in a 48-year-old man. Gray-scale US image demonstrating a focal nodular lesion in liver (solid arrow), which shows a central echogenic component and a peripheral ill-defined hypoechoic ring (target-sign). Multiple other hypoechoic lesions can also be seen (interrupted arrows) in liver. This appearance cannot be distinguished from metastases on imaging, and tissue diagnosis is mandatory in the absence of any known primary malignancyBack to article page
