In the mild PVL ultrasound, there is an increased density around the ventricles which is suggestive of injury. Another head ultrasound should be performed to see if there has been progression.</figcaption> </figure> <p>Although the brain tissue damage may have occurred before birth, during delivery, or in the immediate days following birth, the cysts may take several weeks to appear, delaying a definitive diagnosis. Head ultrasound (HUS) is performed regularly to confirm diagnosis. If cysts are detected, they may appear to resolve themselves over the course of a month or more, but the longer term damage from PVL will likely not appear until months later. Generally speaking, damage from PVL affects motor control and may lead to a diagnosis of cerebral palsy.</p> <figure class="asset-c-80"> <span class="asset-image-title">Cystic periventricular leucomalacia (PVL)</span> <img src="https://assets.aboutkidshealth.ca/akhassets/PVL_cystic_ultrasound_MEDIMG_PHO_EN.jpg" alt="" /> <figcaption class="asset-image-caption">Sometimes there is a progression of from the early changes seen in mild PVL, and cystic PVL develops. Low blood supply causes brain tissue to soften up and eventually die, leaving behind cysts, or holes, filled with fluid.
