1 Introduction The patient was admitted to the hospital with abdominal pain, diarrhea, mucus, and vomiting. After gastroenterostomy edema obstruction, no obvious abnormalities. There was a headache in the near future and no significant abnormalities were seen on the CT scan. Lumbar puncture was performed routinely and cytologically for cerebrospinal fluid. Cerebrospinal fluid was slightly turbid and Paneth was negative. Glucose and chloride levels were normal. The protein was slightly higher (0.5 g/L). Red and white blood cells were not seen. The spider membrane reaction was negative. The cell smears were stained with Wright-Giemsa. The number of abnormal cells in the microscopic examination was different. The size was irregular, the shape was round or irregular, the nucleus was large and eccentric, the nucleus was malformed, the edges of the cytoplasm were uneven, and the nuclear plasma ratio was
