Sixty patients with raised intracranial pressure and lowered attenuation areas around the lateral ventricles ('periventricular lucency', PVL) on CT scanning were reviewed, and compared with a control group of 90 similar patients who did not have PVL. It was confirmed that PVL tends to occur in patients with acute or subacute obstructive hydrocephalus due to a tumour, and is more common in the presence of papilloedema and/or a decreased level of consciousness. Patients with very dilated lateral ventricles did not in general have PVL, but it was frequently seen in association with diastasis of the sutures. Twelve patients with PVL had no other clinical or radiological indication of raised intracranial pressure. Comparison with the control cases did not reveal any reason as to why some patients should develop PVL while others did not.
对60例颅内压升高且CT扫描显示侧脑室周围低密度区（“脑室周围透亮区”，PVL）的患者进行了回顾性研究，并与90例无PVL的类似患者组成的对照组进行了比较。证实PVL倾向于发生在因肿瘤导致急性或亚急性梗阻性脑积水的患者中，并且在存在视乳头水肿和/或意识水平下降的情况下更常见。侧脑室极度扩张的患者一般没有PVL，但PVL常与颅骨缝分离相关。12例有PVL的患者没有其他颅内压升高的临床或影像学指征。与对照病例比较未发现为何有些患者会出现PVL而有些患者未出现的原因。
