一个案件的双边持续增生性原始玻璃体（PHPV）在一个3个月大的男婴，谁有双边白内障，提出。这名儿童因临床怀疑为视网膜母细胞瘤而接受影像学检查。灰阶超声评价显示两个眼球后段均存在回声带，从透镜囊后表面延伸至视盘。多普勒检查显示两个球体中的条带中存在动脉血流。还观察到相关的回声性出血，并经计算机断层扫描证实。大多数PHPV病例是散发性和单侧的，而双侧PHPV是罕见的。本病例的影像学特征提示双侧PHPV的诊断，并与视网膜母细胞瘤相鉴别。这种情况虽然不常见，但在评估双侧白内障时应考虑到鉴别诊断。
A case of bilateral persistent hyperplastic primary vitreous (PHPV) in a 3-month-old male infant, who had bilateral leukokoria, is presented. The child was referred for imaging with a clinical suspicion of retinoblastoma. Gray-scale ultrasound evaluation revealed an echogenic band in the posterior segment of both globes, extending from the posterior surface of the lens capsule to the optic disc. Doppler examination revealed the presence of arterial flow in the band in both globes. Associated echogenic hemorrhage was also seen, which was confirmed by computed tomography. Most cases of PHPV are sporadic and unilateral, and bilateral PHPV is rare. The imaging features in this case suggest the diagnosis of bilateral PHPV and differentiate it from retinoblastoma. This entity, although infrequent, should be considered in the differential diagnosis while evaluating bilateral leukokoria.
