RESUMO
The etiology of congenital hypothyroidism (CH) is often difficult to identify, owing mainly to limitations in currently available diagnostic tests. Characteristics of the distal femoral epiphyseal (DFE) ossification center may provide important information and help identify some causes of CH. We analyzed the contribution of DFE ultrasonography in the investigation of 11 young infants with positive screening for CH. DFE ultrasonography emerged as a simple test that helped indicate the period of onset of CH and, when associated with clinical history, hormone levels, and thyroid ultrasonography, contributed to suggest the etiology of CH.
