- < 75% (hembra), < 65% (macho) : dolicocefálico.

Female patient, 20 years old, gravida one 0 birth coursing 17 weeks pregnant so far without anything relevant. Comes with second level review after being examined in another center where liquid is reported fetus in the abdomen. The sonographic examination shows breech product dolichocephaly (defined by increased anteroposterior diameter due to premature fusion of the sagittal suture, and cephalic index between 65 and 75)
The cephalic indices are:
<75 span=""> % (female), <65 span=""> % (male): dolichocephalic.
75% -80 % (female), 65 % -75 % (male): mesocephalic.
> 80 % (female),> 75 % (male): brachycephalic.
The fetal abdomen is occupied by liquid mass (fetal hydrops) mega-ureter 65>75>and mega-bladder, internal organs (liver, spleen and kidneys look small, hypotrophic, kidneys also showed multiple cysts that occupy the entire parenchyma ( polycystic kidneys ). the femur, tibia and humerus show normal size. absolute absence of amniotic fluid (Oligohydramnios severe) is checked. the mother is blood group a Rh (+), the father does not know his blood or Rh group. We conclude therefore that is fetal malformations incompatible with life and so we explained to the pregnant woman and her mother .Because the mother to have some degree of exoftamos we suspect that the cause could be the blood incompatibility of parents or maternal hyperthyroidism , both should be evaluated, especially for the future.
