PY - 2015 T2 - Diagnostic Imaging of Infants and Children AB - An estimated 2% to 4% of children have clinically significant hypertension. Primary, or essential, hypertension is relatively uncommon in children. Approximately 90% of hypertensive children less than 10 years of age have a secondary form. Eighty percent of secondary hypertension in the pediatric age group is related to renal disease. The most common underlying pathology is a parenchymal disease of the kidneys, such as glomerulonephritis, nephritis, or reflux nephropathy. Only 20% of renal hypertension in children is due to abnormalities of the large renal arteries. There are also various endocrinological conditions that can cause hypertension, including corticosteroid medications, pheochromocytoma, adrenal adenoma, adrenocortical carcinoma, adrenogenital syndrome, and primary aldosteronism (Table 52-1).1 SN - PB - McGraw-Hill Education CY - New York, NY Y2 - 2024/04/16 UR - accesspediatrics.mhmedical.com/content.aspx?aid=1148951764 ER -
