Hepatitis tuberculosis presenting as tumoral disease on ultrasonography.

Macronodular involvement of the liver is a rare manifestation of hepatitis tuberculosis. Two cases of this pseudotumoral form are reported on ultrasonography, demonstrating multiple hypoechoic nodules distributed throughout the liver. The authors state the difficulty in differentiating this form in its atypical presentation from lymphomatous or secondary malignancies. They stress the importance of the bacteriological and/or histological diagnosis which can be performed with fine-needle percutaneous biopsy under ultrasound guidance and which allows effective therapy.
