Adrenal cysts in the newborn.

We report on 2 newborns with adrenal cysts who were treated successfully with an operation. One patient had been well after birth with no adrenal insufficiency. However, 2 large and 2 small cysts were found, all of which were attached to the adrenal gland without a clear vascular stalk. The other patient had adrenal cortical insufficiency. His mother had had gestational diabetes and hypertension during pregnancy. The adrenal cyst was partially resected. Both patients were in good condition 5 years postoperatively.
