“Ultrasound pictures” Renal vein thrombosis (RVT) pediatric

RVT primarily occurs in the neonatal period but may occur in the older child, particularly in association with renal malignancy and amyloidosis.
Classically the sick neonate is noted to develop gross haematuria in association with a palpable abdominal mass. RVT is usually unilateral but may be bilateral and is associated with acute adrenal haemorrhage when left-sided. Sonographically the affected kidney is enlarged and globular and develops an inhomogeneous echogenicity of the renal parenchyma with areas of increased echogenicity due to haemorrhage (Fig. ultrasound images below). Thrombus may be detected in the

encasing vascular structures: it may be difficult to differentiate from lymphadenopathy (Fig. ultrasound images below)
