Adrenal union (fusion)
  • Adrenal glands are fused above the aorta with butterfly or horseshoe shape, with common connective tissue capsule and intermingling of cells
  • Associated with midline congenital defects, including spinal dysraphism, indeterminate visceral situs, bilateral renal agenesis and Cornelia de Lange syndrome (intellectual and growth disabiity, low set ears, antiverted nostrils, spade-like hands with short tapering fingers)
  • Normal histology
  • Unions also to kidney or liver in 0.4-3.0% of unselected autopsies; common capsule, but no intermingling of cells

Adrenal adhesion
  • Adrenal gland is attached to opposite adrenal gland, but with an intervening connective tissue capsule
