[Value of ultrasonics in diagnosing the onset of lymphomatous liver lesions].

Ultrasound and anatomic findings were compared in 128 cases of lymphoma [87 non-Hodgkin lymphomas (NHL), 41 Hodgkin's disease (HD). Lymphomatous or other hepatic anomalies were observed in 40 cases (33 NHL, 7 HD). The 33 NHL lesions included 22 lymphomatous sites and 13 non-lymphomatous pathologies (in particular 5 biliary cysts and 4 cavernous liver hemangiomas). The 7 cases of hepatic anomalies in patients with HD included 6 specific disease sites and 1 cavernous hemangioma. For NHL, the sensitivity of ultrasonography in our series was 72.7% and the specificity 97%. In HD, the sensitivity was 66.6% and the specificity 100%. The value of ultrasound for the detection of lymphomatous liver lesions appears comparable to the results obtained with CT published in the literature; ultrasonography should thus be the first examination performed for subdiaphragmatic exploration during the investigation and follow-up of lymphomas.
