Abstract
The association between external ear abnormalities and renal malformations has been reported previously . There is a general consensus on the need to rule out urinary tract malformation in a child with external ear malformation or when the isolated preauricular tag / pit is accompanied by other dysmorphic features ( Kugelman et al ., 2002 ) . Although many pediatricians pursue renal ultrasonography when patients are noted to have external ear malformations , there is much confusion over which specific ear malformation do and do not require imaging ( Wang et al ., 2001 ) .
