Abstract

A 9 year old boy with Poland's syndrome (absence of the left pectoralis major muscle associated with an ipsilateral malformation of the hand) and isolated growth hormone deficiency, owing to anatomical abnormalities of the pituitary gland, is described. MRI brain scan showed severe hypoplasia of both the sella and anterior lobe of the pituitary gland with absence of the pituitary stalk and ectopia of the posterior lobe. Association of Poland's syndrome and growth hormone deficiency has not been described previously.
