Renal scars masquerading as complex masses in a patient with vesicoureteral reflux nephropathy.

Vesicoureteral reflux can lead to chronic pyelonephritis, renal scarring, and renal failure. We present a case of renal scarring masquerading as bilateral, complex renal masses. A 35-year old woman who was diagnosed with vesicoureteral reflux as a child presented for evaluation of recently developed hypertension and an abnormal renal ultrasound.

Implementation of the STOP protocol for Stroke Prevention in Sickle Cell Anemia by using duplex power Doppler imaging.

Purpose: To compare the results of the nonduplex ultrasonography (US) Stroke Prevention Trial in Sickle Cell Anemia (STOP) with those of transcranial duplex power Doppler US by using the STOP protocol and to correlate abnormal transcranial Doppler findings with magnetic resonance (MR) imaging and MR angiographic findings.

Materials And Methods: One hundred twenty-five asymptomatic patients aged 2-16 years with sickle cell anemia or sickle cell-beta thalassemia were examined by using transcranial duplex power Doppler US with a 2.5-MHz transducer and classified according to STOP criteria.

Prospective pretransplant ultrasound screening in 206 patients for acquired renal cysts and renal cell carcinoma.

Background: Numerous studies have reported an increased prevalence of renal cell carcinoma in association with acquired cystic kidney disease (ACKD). In 1995, the clinical practice guidelines of the American Society of Transplant Physicians for evaluation of renal transplant candidates recommend not screening for ACKD and renal cell carcinoma, on the basis of the low frequency of cancer and reported regression of ACKD after transplantation. The objective of this study was to prospectively evaluate the prevalence of ACKD and renal cancer during renal transplant evaluation.

Mesenteric cystic lymphangioma: radiologic appearance mimicking cystic teratoma.

Lymphangiomas are benign multiloculated cystic tumors. We present radiologic and pathologic findings of a mesenteric lymphangioma containing calcification and mimicking a mesenteric teratoma. This may broaden the differential diagnosis of a cystic mesenteric mass containing calcification.
