Ebb and flow rickets in a premature infant: The Afghan turban sign

Abstract

The pattern of alternating dense and lucent bands, with straight outer edges, at the youngest metaphysis of long bones, the 'Afghan turban' sign, occurs when incompletely treated rickets has recurred and been retreated. Recognition of this, and other, rickets patterns allows the radiologist to influence treatment, as described in a very low birth weight infant.
