Cerebrospinal fluid transparency

Normal cerebrospinal fluid is clear and transparent. When there is a pathological change in the meninges, the cerebrospinal fluid will appear to have varying degrees of turbidity due to the presence of bacteria or cells. The degree of turbidity will vary depending on the type and severity of the disease. Such as purulent meningitis, a large increase in white blood cells can be pustular milky white opacity; tuberculous meningitis, white blood cells in the cerebrospinal fluid increased moderately, can be mild frosty glass. Normal cerebrospinal fluid can also cause mild turbidity caused by red blood cells entering the cerebrospinal fluid during puncture.
