disrup2ons of the nervous system. It's a form of holoprosencephaly

A condi2on in which there is no nose and a proboscis separa2ng two close-set
orbits; associated with holoprosencephaly

Fusion of legs; bilateral renal agenesis is associated with this.
Bladder flap hematoma
Collec2on of blood between the bladder and lower-uterine segment, resul2ng
from a lower-uterine transverse cesarean sec2on and bleeding from the
uterine vessels.
Cys2c teratoma
Mc benign germ cell tumor (<1% malignant); hair/teeth; calcifica2ons; has 2p
of iceberg sign: only the anterior element of the mass is seen, while the greater

car2lage, and hair); typically found in an ovary and usually benign; only the
