Abstract

Replacement lipomatosis of the kidney is a rare disorder in which a massive fatty tissue proliferation occurs within the renal sinus, hilum and perirenal region. Clinical symptoms includes flank pain, hematuria, fever usually associated with urinary tract infection and renal stone. But deep vein thrombosis due to mass effect has not been reported to be associated with replacement lipomatosis of kidney. A 37-year-old male was referred for the initiation of hemodialysis due to chronic rejection of allograft kidney. Collateral superficial veins were observed on his anterior abdominal wall and firm mass was palpable in the right lower quadrant abdomen. Abdominal-pelvis computed tomography revealed huge fatty mass originated from allograft kidney and non-visualization of inferior vena cava with lower density thrombus at both the common femoral veins. We report a rare case of replacement lipomatosis of the kidney complicated by deep vein thrombosis after renal transplantation.
