Cerebrospinal fluid cell dyeing grouping examination for diagnosis of meningeal carcinomatosis

Objective:To study the method of cerebrospinal fluid cytology examination and diagnostic value of meningeal carcinomatosis. Methods: Deploy Hao clan ceii harvestor physio-precipitation method,smear,Wright-Giemsa staining,immersion objective examination cerebrospinal fluid (CSF) cell morphology were usod. Results: Nerv intemal medicine 228 cases examination of cerebrospinal fluid, to alter high power direct eukocyte differential count method ,discovered 7 cases of meningeal carcinoof matosis, detection rate was 3.07% . The biochemistry examination result of 7 meningeal carcinomatosis discem were: adenosine deaminase (ADA) ,glycose normal or degrade ,total protein 1096.4±1088.6mg/L,leucocyte 720.3±1248.6×106/L. Conclusion: Common case of ADA,glycose normal or degrade ,total protein and leucocyte elevated , all should change routine direct cell differential count method to deploy ceii harvestor physio-precipitation method ,staining,immersion objective examination CSF cell morphology .to avoid missed diagnosis meningeal carcinomatosis .
