Application of the International System for Serous Fluid Cytopathology in Cerebrospinal Fluid Cytology

The classification of CSF cytology samples using TIS proved to be feasible and effective. Notably, the majority of samples fell into the NFM and MAL categories, while the AUS and ND categories were rare. These findings suggest that this classification could provide a reliable framework for CSF cytology reporting, improving diagnostic accuracy and potentially aiding in clinical decision-making. Two-Liner: This study offers proof of the value of the application of The International System for Serous Fluid Cytopathology in the cytological interpretation of cases of cerebrospinal fluid.
