The sonograms, chest radiographs, and CT scans of 40 consecutive patients with Hodgkin (n = 29) and non-Hodgkin (n = I 1) lymphoma obtained before and after completion of therapy were analyzed blindly and independently by three radiologists and compared with clinical outcome. Nine patients were treated with radiotherapy, 12 with chemotherapy, and 19 with combined therapy. Therapeutic response was assessed from all available clinical and biochemical findings as well as from the combined results of all imaging studies performed on further follow-up. The sonograms showed obvious changes in the size and echogenicity of the mediastinab bymphomas that corresponded cbosely with the response to therapy. Sonography showed complete regression of the bymphomas in 30 patients who had complete remission. In five patients with incomplete remission, sonographic diagnoses were correct. All lymph nodes, irrespective of size, detected with sonography after a phase of complete remission indicated recurrence (five patients).

Thirteen out of 19 hepatic lesions and nine out of 11 splenic lesions corresponded to a nodular lymphomatous involvement. The remaining cases involved benign focal lesions of the liver and spleen. The vast majority of the hepatic and splenic lymphomatous nodules had a hypoechoic pattern with indistinct edges. Target lesions of the liver were seen only in non-Hodgkin's lymphoma. Echogenic lymphomatous nodules could not be detected. All echogenic lesions (three) were biopsied and found to be benign. Whereas a focal liver involvement almost always occurred in combination with hepatomegaly, only two out of nine patients with splenic foci had splenomegaly. The response of hepatic and splenic lymphoma to chemotherapy is described from follow-up examinations in 11 cases. Because of the inherent risk of over-treatment of the false positive interpretation of hepatic nodules, the large-scale use of needle biopsy in sonographically equivocal lesions is strongly advocated.
