The clinical and radiographic features of massive neonatal adrenal hemorrhage

A correct diagnosis of neonatal adrenal hemorrhage may be established without surgery when the clinical findings of unexplained jaundice and an abdominal mass are combined with the radiographic findings of a homogeneous, radiolucent, oval or triangular suprarenal mass seen on the total-body-opacification phase of the excretory urogram. The affected kidney will be displaced and will usually show a concave pressure defect on its superior pole. Follow-up radiographs will show first the return of the urogram to normal and in a few weeks calcification at the site of the previous adrenal hemorrhage. Three cases are presented.
