Utility of intraoperative squash cytology in diagnosis of paediatric central nervous system lesions

Role of squash cytology in intraoperative diagnosis of central nervous system lesions has been well established. Intraoperative diagnosis is especially important in paediatric CNS lesions as decision regarding gross total resection or near total resection or subtotal resection is crucial and radiotherapy and chemotherapy are best avoided in this age group. The aim of this study was to evaluate the utility of squash cytology of CNS lesions in paediatric age group and to assess its diagnostic accuracy, sensitivity, specificity, positive predictive value and negative predictive value.
