A unique case of retinoblastoma masked by retinal detachment diagnosis and management.
A 4-year-old Latin American boy presented with a history of loss of vision of his left eye for 7 months. He was followed by different ophthalmologists and diagnosed with a retinal detachment. Computerized tomograms and magnetic resonance imaging demonstrated a large calcified left eye and markedly enlarged optic nerve. Based on these radiologic findings diagnosis of retinoblastoma was strongly suspected. Initially enucleation was not done because it was thought that cutting through the involved optic nerve would cause dissemination. The patient was treated with chemotherapy which resulted in marked response. Following normalization of optic nerve and after irradiation the eye was enucleated. The diagnosis of retinoblastoma was confirmed. No tumor was found in the optic nerve. The importance of imaging studies in diagnosis of retinoblastoma and the role of chemotherapy in the treatment of primary retinoblastoma are emphasized.
