Acute renal failure due to non-Hodgkin lymphoma infiltration of the kidneys detected by ultrasonography and confirmed by positron emission tomography

Abstract

Acute renal failure (ARF) as a consequence of non-Hodgkin lymphoma infiltration of the kidneys (LIK) is an uncommon complication of non-Hodgkin lymphoma. In literature, ARF due to LIK is reported in progressive disease. A case of non-oliguric acute renal failure secondary to relapse of large B cell non-Hodgkin lymphoma primarily localized in the mediastinum is reported. LIK of both kidneys was diagnosed by ultrasonography, computer tomography scan and 18-fluorodeoxyglucose positron emission tomography. No other causes for renal failure were found. The prognosis of renal involvement in relapsed non-Hodgkin lymphoma is poor, as is demonstrated by our case.
