Mastopathy-mimicking ultrasonographic appearance in a case with Burkitt's lymphoma

We report a case of Burkitt's lymphoma, which was suspected to involve both breasts. US showed a replacement of the normal breast tissues by a diffuse ly mixed or mottled pattern of echo texture, associated by hypoechoic cyst- like masses with slight internal echogenicity. This pattern was indistingui shable from the sonographic changes produced by a mastopathy. These finding s disappeared after successful chemotherapy for the Burkitt's lymphoma, sug gesting that the ultrasonographic pattern of mastopathy was caused by the i nfiltration of the breast tissues by the lymphomatous cells.
