Pituitary stalk interruption syndrome
A 5-year-old boy presented at the department of Pediatrics because of parental concerns about his delayed growth which had been slowing since the age of 2.5 years. The patient had no significant familial, perinatal or past medical history. At clinical examination, no abnormalities were present. His...
