Xanthochromia

• abstract: Xanthochromia [from the Greek xanthos (ξανθός)=yellow and chroma (χρώμα)=colour], is the yellowish appearance of cerebrospinal fluid (which envelops the brain) in particular medical conditions, especially subarachnoid hemorrhage. The most effective test for SAH is computed tomography (CT, a type of brain scan), but this identifies only 98% of cases in the first 12 hours after the symptoms and becomes less useful afterwards.
