Normal lymph nodes have a reniform shape, a uniformly hypoechoic cortex with a maximal thickness of 3 mm, smooth margins, and a central fatty hilum (Fig 1). Findings of cortical thickness in excess of 3 mm, eccentric thickening, irregular margins, and encroachment on or displacement of the fatty hilum are suggestive of a pathologic process."
