title: Calcific thrombi of the inferior vena cava in infants and children.
abstract: Calcified caval thrombus should be considered in any infant or child where calcifications are noted in the high right retroperitoneal area on plain x-rays of the abdomen. Although typically bullet-shaped in configuration, the calcium distribution in the neonate may be atypical or incompletely developed, suggesting neuroblastoma. Definitive diagnosis can be made by inferior vena cavagram. As no deaths or complications have been attributed to the lesion in the cases thus far reported, no specific treatment is recommended.
