摘    要:目的:探讨CT在永存原始玻璃体增生症(PHPV)诊断中的价值。方法:回顾性分析5例PHPV的CT表现。结果:5例(5眼)PHPV均表现为患侧小眼球,玻璃体密度增高,玻璃体内见条带状或锥形软组织影,从晶状体后部连接到视乳头;4例4眼患侧眼球晶状体不同程度变形、轮廓不光滑、晶状体位置前移、前房变浅、晶状体密度增高,5例5眼软组织内均未见高密度钙化灶。结论:小眼球、玻璃体内见条带状或锥形软组织影,从晶状体后部连接到视乳头,软组织内未见高密度钙化灶为PHPV的CT表现。CT扫描可清晰显示眼内病变组织,可为PHPV的诊断和鉴别诊断提供客观可靠的影像学依据,具有极其重要的价值。

Abstract:Objective:To evaluate the diagnostic value of CT in persistent hyperplastic primary vitreous(PHPV).Methods:The CT findings of 5 cases with PHPV were analyzed retrospectively.Results:CT scan showed all 5 cases(5 eyes)having microphthalmic,high density signal of vitreous body,and a girdle-shaped or cone soft-tissue band which located from the posterior lens to the papilla optica,and also showed 4 cases(4 eyes)having lens crystalline deform,lens outline not smooth,lens antedisplacement,shallow anterior chamber,high density of lens.But there is no high-density calcification focus in the soft tissue in all 5 cases(5 eyes).Conclusion:The microphthalmus,a girdle-shaped or cone soft-tissue band which located from the posterior lens to the papilla optica,without high-density calcification focus in the soft tissues are the CT manifestation of PHPV.CT can display objective basis for clinical diagnosis and offer valuable reference in diagnosing and differential diagnosing of PHPV.
Keywords:vitreoretinopathy  proliferative  tomography  X-ray computed
