CT
Axial CT of the abdomen and pelvis demonstrates an enlarged right kidney with total occlusion of the right renal vein. The thrombus can be observed as a filling defect in the nephrographic phase, with decreased enhancement of the right kidney. Perinephric fat stranding and oedema are visible in the perirenal space. Thrombus extends into the IVC.
Pulmonary emboli can be visualised in the right and left lower lobe segmental pulmonary arteries. A left-lower lobe wedge-shaped opacity extending to the pleura is compatible with pulmonary infarction. A small, left-sided pleural effusion is also present.
