Rescue intra-arterial chemotherapy in unilateral multirelapsed peripapillary retinoblastoma: Decision making and the role of MRI

Abstract

Introduction:

In this case report we report our experience with rescue intra-arterial chemotherapy in a case of multi-relapsed peripapillary Retinoblastoma (RB) and the importance of high resolution MRI in detecting possible optic disc infiltration.

Case report:

In 2007, a 14 month-old caucasian girl was referred to our ocular oncology unit for leukocoria. Only left eye was interested, with a single mass of the posterior pole. Patient underwent six cycles of systemic chemotherapy and focal laser consolidation. Several relapses occurred during follow-up. Selective intra-arterial chemotherapy (SIAC) with Melphalan was performed and type IV remission was achieved. A new relapse occurred next to the optic disc. MRI was performed and we decided to try to save the globe with a rescue cycle of SIAC.

Conclusion:

MRI has demonstrated to be useful in decision making in RB, giving us a last chance to save the globe.
