Choroid plexus and ependymal cells were only demonstrated in 10 of a series of 2620 CSF cytograms. Choroid plexus cells sometimes stained positive for acid phosphatase while in ependymal cells this enzyme activity was not observed. Choroid plexus and ependymal cells in CSF were found to be associated with various neurological disorders involving mainly the brain stem and spinal cord. This is probably due to the higher chance of sedimentation of viable cells in the lumbar sac in these conditions. Loss of these cells might explain the incidental observation of granular ependymitis in post-mortem brains.
在2620份脑脊液细胞图谱系列中，仅在10份中发现脉络丛和室管膜细胞。脉络丛细胞有时酸性磷酸酶染色呈阳性，而室管膜细胞未观察到这种酶活性。脑脊液中的脉络丛和室管膜细胞与主要累及脑干和脊髓的各种神经系统疾病有关。这可能是由于在这些情况下，活细胞在腰段蛛网膜下腔沉降的可能性更高。这些细胞的丢失可能解释了在尸检大脑中偶然观察到的颗粒性室管膜炎。
