Abstract

Authors retrospectively analyzed CT findings of 10 cases which proved retinoblastoma by pathology from May in1983 to August in 1986 at Yeungnam University Hospital. The results obtained were as follows: 1. The age at timeof diagnosis was 1-5 year old. 2. In 9 cases(9/10), retinoblastoma was unilateral. 3. Of all 10 cases, 8 cases revealed intraocular calcification. 4. At time of diagnosis of retinoblastoma, optic nerve involvement with orwithout intracranial extension were 2 cases. The diagnosis of retinoblastoma ca be made clinically, but CT isvaluable adjunct in differential diagnosis and management as well as diagnosis of retinoblastoma. In additon, orbital CT can be used to determine if there is retrobubar extension of retinoblastoma, involvement of CNS, and development of secondary orbital tumors.
