Cytology of the cerebrospinal fluid in patients with Hodgkin's disease or malignant lymphoma.
The cerebrospinal fluids (CSF) of 18 patients with Hodgkin's disease and 33 patients with malignant lymphoma were evaluated for the presence of malignant cells. The CSF  cytology was correlated with the neuropathologic findings at surgery or autopsy. In the 51 patients included in the study there were seven false-negative CSF cytodiagnoses. Methods to improve detection in the false-negatives will be discussed. There were two false-positives. Explanations for the two false-positive cytodiagnoses will be presented. It is concluded that cytological examination of the CSF in patients with Hodgkin's disease and malignant lymphoma is a useful and reliable diagnostic tool.
