A Case Series of Holoprosencephaly
Holoprosencephaly is congenital brain anomaly due to incomplete separation of two cerebral hemispheres. It has three subtypes which are alobar, semilobar and lobar. Degree of severity is decreased from alobar, semilobar then lobar holoprosencephaly. The embryogenesis incidence rate is 1:250. Because of spontaneous abortion, the lower occurrence rate is seen at 1:16000 in a live birth. The patient's survival rate depends on the extent of the deformity and also the type of holoprosencephaly. In this case series, we include radiological descriptions of the holoprosencephaly of all three subtypes.
