The management of Cushings' syndrome is very much a combined effort between the Charing Cross and Hammersmith sites. The selective petrosal and adrenal venous sampling and adrenalectomies are carried out at the Hammersmith site. The pituitary surgery for ACTH secreting adenomas occurs at the Charing Cross site. The full range of adrenal, pathology is seen at both sites including Cushings' syndrome, congenital, adrenal hyperplasia, androgen secreting tumours and primary and secondary hypoadrenalism.
