FiguresFigure 1(A) Unstained wet mount (40×) of ependymal cells. (B) Unstained wet smear preparations (400×) of the polypoidal tissue showing round ciliated cells. (C) Unstained wet smear preparations (400×) showing round ciliated columnar cells. (D) Haematoxylin and eosin (H&E) stained smear (400×) showing a single cell with cilia and round to oval nuclei. (E) H&E stained smear (400×) showing single columnar cell with prominent brush border and round nuclei.Case 1 was an 18-year-old college student who presented with complaints of fever, headache, and vomiting of 2 days duration. On the day of admission, he had altered sensorium in the form of increasing drowsiness. The patient had visited a water park a few days before symptom onset. On examination, signs of meningeal irritation were seen in the form of neck stiffness. Magnetic resonance imaging of the brain showed features suggestive of meningoencephalitis predominantly involving the right basifrontal lobe.??Keywords: Detached ciliary tufts, Ciliated ependymal cells, Ciliocytophthoria, Pseudoparasites
