A Devastating Diagnosis: Anencephaly With Unexpected Fetal Heartbeat.

This case report describes a severe birth defect called anencephaly in a fetus at 18 weeks of pregnancy. Anencephaly occurs when the upper part of the baby's brain and skull do not form correctly. This condition is usually detected earlier in pregnancy, often in the first three months. However, this case was discovered at 18 weeks, highlighting the need for careful monitoring throughout pregnancy. The unique aspect of this case is that most pregnancies with anencephaly do not progress this far. This later diagnosis provides important information about the different ways the condition can develop. By studying cases like this, healthcare providers can improve prenatal care and potentially detect such defects earlier, even in the later stages of pregnancy. Overall, this report emphasizes the importance of continuous monitoring during pregnancy and offers insights that could lead to better diagnosis, care, and support for families facing similar situations.
