Hydranencephaly following carbon monoxide poisoning during pregnancy: An uncommon and potentially fatal complication in infant.

BACKGROUND

Hydranencephaly is a rare malformation of the brain system with an incidence of 0.5 per 1000 births. Its principal etiologies are bilateral occlusion of the internal carotid arteries and congenital infections.

CASE: We reported an uncommon case of hydranencephaly diagnosed in 50-day old infant and attributable to carbon monoxide (CO) poisoning during the first trimester of pregnancy.

CONCLUSIONS

We recommend a prompt diagnosis and management of CO poisoning in pregnant women since it can dramatically affect both the fetus and mother.
