Transient obstruction of the kidney and hypertension due to neonatal adrenal hemorrhage. Case report.
A case of neonatal adrenal hemorrhage associated with transient obstruction of the kidney and hypertension is reported. Sonography demonstrated a mass in the right suprarenal area, consistent with hemorrhage into the adrenal gland. DTPA renal scan showed prolonged retention of the injected material in the right kidney, consistent with obstructed outflow from the renal collecting system. Gradual decrease in the size of the suprarenal mass was associated with relief of the renal obstruction as evidenced by a normal repeat renal scan, and a return to normal of the blood pressure. It appears that the cause for the hypertension was the acute renal obstruction, which was due to either direct pressure on the proximal ureter by a large adrenal mass or secondary to displacement of the kidney by the mass resulting in kinking of the proximal ureter.
