Objective To investigate the clinical characteristics and CT findings of retinoblastomas in children. Methods The clinical data and CT findings of 35 children (36 eyes) with retinoblastomas confirmed by operation and pathology in our hospital from July 2010 to July 2015 were retrospectively analyzed and summarized. Results In the study, 25 patients (26 eyes) in phaseⅠaccounted for 72.22% (26/36), 10 cases (10 eyes) in phaseⅡfor 27.78% (10/36) and a case in phase Ⅲ for 2.78% (1/36). Calcification within masses was the typical CT sign of retinoblastomas. Conclusion Masses and calcification within eyeballs are the characteristics of retinoblastomas in children. The sensitivity of CT diagnosis to retinoblastomas is high, which is the first choice for the clinical diagnosis of retinoblastomas.
