Intra-abdominal Hypertension as a Cause of Oliguric Acute Kidney Injury in a Patient with Chronic Lymphocytic Leukemia.

Acute kidney injury (AKI) is a well-known complication in patients with chronic lymphocytic leukemia (CLL). It could occur via diverse mechanisms such as leukemic infiltration, extrarenal obstruction, tumor lysis syndrome, glomerular diseases, and medication side effects. The incidence of kidney disease at the diagnosis of CLL is about 10%. We report a case of AKI, in a patient with a known history of CLL, due to abdominal compartment syndrome, caused by extremely enlarged intra-abdominal lymph masses. To the best of our knowledge, no case of AKI due to such cause has been reported so far.
