Microscopic findings in CSF and urine samples before treatment. a: Inverted microscopic images of the patient’s CSF. a–c: Irregularly shaped cells with vacuoles. c: Irregularly shaped cells with finger pseudopodia. d: Cells with transparent circular shells; no structures were observed. e: Black sphere. b: Differential interference contrast light microscopic images of the patient’s urine. f–h, j, l, n: Spherical cells. k: Cells with huge vacuoles. m: Cell with fan-shaped pseudopodia. Some “cells” cluster together. Scale bars: 10 μm
