Cytology of Cerebrospinal Fluid in Retinoblastoma - Possibility of Early Detectionof Tumour Dissemination into the CNS

Overview

Retinoblastoma is a malignant tumourous disease which occurs in childhood. Themost important factors which influence possible cure of patients with a retinob-lastoma are early detection of the disease, correct diagnosis and adequate therapy.In the submitted case-record the authors provide evidence of the importance ofcytological examination of cerebrospinal fluid which is important in retinoblas-toma in particular for the follow-up of treatment. Cytological examination ofcerebrospinal fluid in this type of tumour is very reliable and can reveal infiltra-tion of tumour cells into the CNS much sooner than imaging methods.
