Oligocytosis

Lymphocytic oligocytosis or lymphocytic pleocytosis, usually to a mild degree—simultaneously a plasmocytic response occurs. 

Serous neuroinfections—the appearance of lymphocytic pleocytosis or lymphocytic oligocytosis is present. In this case, the element count is higher than 100/3 /U.1 (35//U.1) and the probability of the diagnosis of multiple sclerosis is very low. 

Monocytic oligocytosis and monocytic pleocytosis—in multiple sclerosis this is practically always a reactive manifestation after administration of intrathecal drugs. 

Mild mixed pleocytosis with prevailing segments or granulocytic oligocytosis— it may or may not progress rapidly into the next stage. 

Lymphocytic oligocytosis— in its chronic stage plasmocytic response is usually present. 

Note Occasionally, the manifestation of monocytic oligocytosis is present, which mimics the cytological findings in Guillain-Barr6 syndrome. 

Polyradiculoneuritis Guillain-Barre—the manifestation of monocytous oligocytosis is present and is practically indistinguishable from certain forms of neu-roborreliosis the syndrome of proteinocytological dissociation is also present, and it is usually distinctly expressed. The best differentiation can be obtained by the presence of an antibody response in cerebrospinal fluid in neuroborreliosis. 

Other neurological diseases accompanied by the manifestation of monocytic oligocytosis this is the most complicated issue of cytological diagnostics in CSF. Borreliosis can be differentiated again by the presence of an antibody response in cerebrospinal fluid. 

Lymphocytic Oligocytosis. Lymphocytic oligocytosis is characterized by the presence of a larger number of activated lymphocytic elements and, in the case of a chronic course, even of plasma cells. It appears in association with multiple...
