Spurious pleocytosis.

摘要

A 50-year-old woman with recently diagnosed stage IV diffuse large B-cell lymphoma had been started on combination chemotherapy. One month later, she presented with a history of progressive neurological symptoms characterized by left hemiparesis and right facial nerve palsy. A manual cell count on a cerebrospinal fluid (CSF) sample revealed a white cell count of 0.006 X 10~9/L. The white cells had the appearance of malignant lymphocytes. CSF protein was 1.78 g/L (range, 0-0.4 g/L).
