CT在视网膜母细胞瘤与其他出现白瞳症的相象的病变的检查和鉴别诊断方面具有重要意义。在加拿大多伦多儿童病院,用高分辨力CT研究了45例视网膜母细胞瘤病人,均显示有眼内钙化的表现,而其他相类似的病变,如Coats病,永存性初发玻璃体增生症(PHPV),弓蛔虫病,显性渗出性玻璃体视网膜病变(DEVR)以及青少年性脉络膜黄色肉芽肿等,没有看到任何钙化的征象,故此,年幼病人疑为视网膜母细胞瘤时,CT检查如能显示钙化,则可作出诊断,否则,可能是其他相类似的病变。
CT in the diagnosis of retinoblastoma and other lesions similar to white pupil disease is of great significance. Forty-five patients with retinoblastoma were studied with high-resolution CT at the Children’s Hospital of Toronto, Canada, showing intraocular calcification, while other similar lesions, such as Coats disease, persistent primary vitreoretinopathy (PHPV ), Ascariasis, DEVR, and juvenile choriocarcinoma did not show any signs of calcification. Therefore, when a young patient is suspected to have retinoblastoma, CT examination such as Can show calcification, you can make a diagnosis, otherwise, may be other similar lesions.
