Abstract

F. Cruz Villalon, MD, J. Escribano Fernandez, MD, and T. Ramirez Garcia, MD Kidney infiltration by lymphoma is not a rare condition. Some authors have stated that this can happen in about 35.5% to 52% of cases in the late stage of the disease.’ Many radiological patterns of kidney lymphoma have been described in recent years, but just a few reports refer to the peripheral “hypoechoic halo” as a way of kidney infiltration for this illness. We present two cases in which we have seen this rare finding, and discuss the possible way of dissemination. CASE REPORTS Case 1 ment, the patient recovered, and on the follow-up ultrasound examination the hypoechoic rim and most of the lymphadenopathy had disappeared. The patient was discharged and periodically reviewed by the hematology service; she has remained well. Case 2 A 57-year-old woman was admitted with epigastric pain and vomiting. Clinical examination revealed neck and inguinal lymphadenopathy. Laboratory tests showed elevated levels of urea and creatinine.
