Written by Medicover Team and Medically Reviewed by Dr Murali Krishna Nagendla , Pediatric Surgeon

Exencephaly is a rare and severe congenital neural tube defect in which the developing brain is located outside the skull due to the absence of the cranial bones. The exposed brain tissue is vulnerable to damage during fetal development, and the condition often progresses to anencephaly before birth. Exencephaly is usually detected during prenatal ultrasound examinations. Early diagnosis, appropriate prenatal care, and genetic counseling help parents understand the condition, its prognosis, and available management options.

What are the Symptoms of Exencephaly?

Exencephaly is a rare condition that affects infants during development. It involves the abnormal formation of the skull and brain. Symptoms typically manifest in a distinct manner that reflects the complexity of the condition.

The signs are often visible and can indicate the presence of this serious birth defect. Early detection and intervention are crucial for managing the condition effectively.

What are the Causes of Exencephaly?

Exencephaly is a rare condition that occurs during fetal development. It is primarily caused by a failure of the neural tube to close properly, leading to the exposure of the brain tissue outside the skull.

Other factors such as genetic mutations or environmental influences may also contribute to the development of exencephaly. Early detection and proper prenatal care are crucial in managing this condition.
