[14] Our patient did have evidence of possible bleeding as reflected by the xanthochromia in the CSF, as well as evidence of a venous infarct as indicated by the occipital low-density area on CT of the brain.
Shah and colleagues (3) also emphasized using xanthochromia by spectrophotometry rather than visual techniques.
Pseudo-SAH should be considered in patients with suspected SAH on CT scan of the head whose lumbar puncture does not demonstrate xanthochromia or in whom the clinical history is atypical for SAH but suggestive of another diagnosis, such as infection.

These include elevated opening pressure of the lumbar puncture, the presence of red blood cells (RBCs) in the CSF, and the presence of xanthochromia in CSF.
No plasma abnormalities such as haemolysis, turbidity, chylosis, xanthochromia or jaundice were seen on visual inspection.
It is often difficult if not impossible to distinguish between SAH and TLP (1, 2) by available CSF tests such as (a) measurement of xanthochromia of the supernatant after centrifugation, (b) counting of erythrocytes in the first and last tubes of collected CSF, or (c) searching of CSF microscopically for crenated erythrocytes (3-5).
Lumbar puncture to detect red blood cells acutely or xanthochromia subacutely may be necessary when the clinical history is convincing and a CT scan is negative.
The opening pressure was modestly elevated at 28.5 cm but no xanthochromia was noted.
Cerebrospinal fluid (CSF) obtained by cisternal puncture showed slight xanthochromia; a nucleated cell count of 2094/[micro]L (54% lymphocytes); glucose, 2 mg/dL; and protein, 368 mg/dL.
Q Our pathologist is interested in offering a semiquantitative assay for cerebrospinal fluid (CSF) xanthochromia. Other than visual inspection, is there an available method for this?
