Morphological characteristics of tumor cells in cerebrospinal fluid of Meningeal Carcinoma

Objective:To study the morphological characteristics of cerebrospinal fluid tumor cells with meningeal metastasis of different malignant tumors and its significance in cytological diagnosis.Methods:55 cases of meningeal carcinomatosis were analyzed and studied in recent 3 years,including clinical and imaging data,determination of glucose and total protein in cerebrospinal fluid of the first lumbar puncture and morphological characteristics of tumor cells.Results:Clinical data showed that all patients had obvious headache,dizziness and memory loss in recent 2-3weeks,including 6 cases with nausea and vomiting,2 cases with mental disorder and 1 case with epilepsy.Imaging showed that 52%of meninges had enhancement focus or nodular enhancement focus.The WBC count,glucose and total protein in cerebrospinal fluid of the first lumbar puncture were abnormal in varying degrees.The positive rate of tumor cells detected by cytology was 94.5%,and no primary focus was found in 7.3%.Conclusion:The morphological characteristics of CSF tumor cells are not only an important basis for cytological diagnosis,but also an important reference for judging the primary focus.
