OBJECTIVES: Growth hormone deficiency (GHD) is a major problem among children with short stature. In this study, the role of brain magnetic resonance imaging (MRI) in defining the underlying defects among short children with GHD is evaluated. METHODS: In a cross-sectional study, data of 158 children were evaluated. Growth hormone (GH) levels were measured using stimulating tests and brain MRI with gadolinium contrast was applied, as well. RESULTS: Some 25.3% of patients had GHD with a mean age of 8.01±3.40 years. MRI results showed 35 as normal, four with pituitary hypoplasia, and one with microadenoma. The MRI results were significantly associated with GH levels and presence of other endocrine disorders. There was a significant association between prenatal disorders and patients' bone age delay. CONCLUSIONS: In patients with severe GHD and patients with multiple pituitary hormone deficiencies, MRI is more likely to be abnormal, and bone age is much delayed in patients with history of prenatal disorders.
