A case report is presented of a Wilms' tumour in a three-year-old child. Direct intravascular extension into the heart led to a fatal outcome. Though a rare complication, clinical suspicion, combined with appropriated investigation and management, should lead to salvage of such a patient (AU)

The authors have studied the radiographic appearances of two of their patients with circumcaval ureter and reviewed the findings in a further 87 cases reported in the literature. They define two types of patterns: (a) The slightly commoner form has a moderate or severe hydronephrosis and an 'S' or 'fish-hook' deformity of the ureter at the point of obstruction. They demonstrate that the point of obstruction is placed some distance from the lateral margin of the inferior vena cava. (b) The second form has a mild hydronephrosis and a 'sickle-shaped' curve of the ureter at the point obstruction. The obstruction coincides with the lateral margin of the inferior vena cava in this type. The generally accepted explanation that pressure by the inferior vena cava explains the second type, but not the first. The cause of the hydronephrosis in the first form is not clear. The authors suggest that it is due to an associated anomaly in the development of the ureter where it crosses the lateral border of the psoas muscle. (AU)
