The tiny vessels that are found in abundance in some areas of a developing baby’s brain can sometimes rupture, causing bleeding. These small haemorrhages appear to cause no long-term problems.
Larger bleeds can occasionally occur, and doctors caring for your baby will monitor this by carrying out regular ultrasound scans. These larger bleeds may limit blood flow to certain areas of the brain. This means that those areas might not receive enough oxygen. Sometimes the flow of fluid from the brain to the spinal cord becomes blocked by the clots formed by the blood and the cells in this area then die and a small fluid-filled pocket forms there instead. Exactly how this might affect your baby will depend on where this ‘cyst’ is located. The doctors will explain what is happening and what this might mean for your baby.
