CYSTIC ADRENAL MASSES IN THE NEONATE ASSOCIATED WITH HEMIHYPERTROPHY AND THE RELATION TO THE BECKWITH-WIEDEMANN SYNDROME

We report 2 cases of unilateral, multilocular, cystic adrenal masses in neonates. Both patients demonstrated somatic hemihypertrophy, which is considered to have the same implications as the Beckwith-Wiedemann syndrome in terms of tumor risk. Pathological examination showed multiple, adrenal cysts without evidence of tumor or routine adrenal hemorrhage. This finding appears to represent a previously unreported association between the spectrum of hemihypertrophy/Beckwith-Wiedemann syndrome and benign cystic adrenal disease.
