Caudal regression syndrome (CRS) is a very rare and unusual disorder affecting the lower part of the body along with multiple systems'involvement. It is mostly found in association with maternal diabetes mellitus during pregnancy; but there is a rare familial form of the disorder, as well. We describe a newborn who presented with the classic clinical and radiologic features of CRS along with bilateral microtia. Our search of the available English language literature did not reveal any such association of CRS with microtia.
