CASE 238: HBV PATIENT with 2 SIDE KIDNEY TUMORS, Dr LÊ THANH LIÊM, MEDIC MEDICAL CENTER, HCMC, VIETNAM.

  Male patient 34yo from  Binh duong province in follow-up  from HBV infection since 2006. He had got 2 kidney cysts and nothing abnormal, but now B-mode ultrasound detected kidney tumors on his 2  sides. Both 2 kidney tumors hyperechoic, homogenous seem to be looked like AML tumor. But they were different on color Doppler, hypervascular, with venous and arterial patterns, maybe oncocytoma or RCC (renal cell carcinoma).

On 3 D ultrasound reconstruction  the left kidney tumor more clear than on B-mode ultrasound.
And elastographic ultrasound (ARFI) proved tumors  more hard than kidney parenchyma.

 

CT proved 2 kidney tumors on 2 sides of one patient.

 

 

He underwent 2 operations for removing 2 kidney tumors, on left side first, partial nephrectomy, with microscopic result of papillary RCC, and right one, total nephrectomy for pRCC again after half of month.

 

pRCC is a unusual kidney tumor, mimicking AML on B-mode ultrasound so we should  use color Doppler to examine kidney tumors.
