NEONATAL RENAL VENOUS THROMBOSIS - A CASE-REPORT DESCRIBING SERIAL SONOGRAPHIC CHANGES

Neonatal renal venous thrombosis (NRVT) is a serious complication of n ewborns. Ultrasound is most useful in detecting NRVT. However, there i s no detailed description of the evolution of ultrasound finding in NR VT. Here we report a patient with NRVT with complete ultrasound follow -up. Perivascular streaks were first seen at 3 days of age with a diff usely enlarged and echogenic right kidney. Echolucency then gradually appeared over the medulla area with shrinking renal size. Concomitant loss of renal function was evidenced by dimercaptosuccinic acid scan. The kidney became contracted at the age of 1 year. Since the pathognom onic perivascular streaks were present for only a few days, early ultr asound scanning should be performed for every newborn suspected of hav ing NRVT.
