Pancreatic pseudocysts have not been reported to occur in the fetus or
newborn. The authors report two cases of histologically proven pancre
atic pseudocysts in neonates, which were detected using prenatal ultra
sonography. Surgical management included external marsupialization fol
lowed by internal drainage in one case, and excision in the other. Bot
h patients ultimately did well. The etiology of these lesions remains
unclear. Copyright (C) 1996 by W.B. Saunders Company
