Acrania-exencephaly sequence

Case contributed by Dr Mohd Imran


Abdominal pain. Inadvertently radiograph taken.

Patient Data

Age: 24 weeks

Radiograph showed surprisingly a fetal skeleton with probably absent cranial bones.


Irregular outlined brain patter protruding freely into amniotic fluid is seen, with absence of cranial vault.

Case Discussion

Neural tube defects affect 2.6 percent per 1000 of births with spina bifida and anencephaly accounts 95% of all NTD'S

Anencephaly is absent of cranial bones and exposed rudimentary brain tissue. Polyhydroaminos is  commonly associated with anencephaly due to  absence of pituitary control over urine formation.

Anencephaly is prevalent in low socio-economic strata due to lack of  folic acid supplementation during pregnancy.
