Usually it closes between the second and sixth month of life. Haemorrhage of CSP is a rare entity. Only two cases of hemorrhage in the abnormal dilated CSP have been previously reported in full term neonate.

Our baby was discharge at hospital a 16 days of life in good clinical conditions and the MRI at 3.5 months of life showed improvement brain anatomy.
