Retroperitoneal tumors in children; roentgen diagnosis.

A study was undertaken to determine whether there are any features of retroperitoneal tumors in children that might be demonstrated on roentgenograms to aid in identifying them preoperatively. Study was limited to Wilms' tumor of the kidney and neuroblastoma. Calcification was found in 57 per cent of the neuroblastomas and in only 12 per cent of Wilms' tumors. Calcifications in neuroblastomas differed from those in Wilms' tumors. Calcification in neuroblastoma was more frequent in older children than in the younger ones. The kidney was frequently displaced by both types of tumor. However, the neuroblastoma always displaced the kidney downward, or downward and slightly outward. In most instances, the Wilms' tumor also displaced the kidney downward and outward, but in some instances upward and medially. This, of course, depended upon the site of origin of the tumor. There was a distortion of the intrarenal structures in 75 per cent of the cases of neuroblastoma and in 71 per cent of the cases of Wilms' tumor.

Extraperitoneal pneumography; a preliminary report.

The presence of a gas in the retroperitoneal tissues makes possible a radiologic visualization of retroperitoneal organs and masses. Retropneumoperitoneum is accomplished by the injection of oxygen at low pressure into the tissues lying between the coccyx and the rectum. The technique of injection is simple and no complications have occurred with the first 30 cases. This method is particularly useful in outlining the kidneys and adrenal glands.
