title: [Magnetic resonance imaging of pituitary hyperplasia in a child with growth arrest and primary hypothyroidism].
abstract: We report a case of pituitary hyperplasia in a child presented with significant growth arrest and laboratory evidence of hypothyroidism. Magnetic resonance imaging (MRI) revealed symmetrical pituitary enlargement seemed to be macroadenoma. After thyroid hormone replacement therapy, the child's height increased and pituitary enlargement regressed. Awareness of MRI appearance of pituitary hyperplasia in children with laboratory evidence of hypothyoidism might avoid misdiagnosis for pituitary tumor, which may also manifest as growth disorder, obviating unnecessary surgery.
