AB Cerebral  spinal  fluid  (CSF)  is  normally  colorless  and  clear.  Analysis  provides  clues  to  infectious  diseases  (meningitis,  encephalitis,  abscess)  and  noninfectious  diseases  (subarachnoid  hemorrhage,  Guillain-Barré  syndrome,  transverse  myelitis,  idiopathic  intracranial  hypertension,  vasculitis,  carcinomatosis,  multiple  sclerosis,  paraneoplastic  syndromes).  The  presence  of  xanthochromia  (see  Fig.  25.58)  in  the  context  of  recent  onset  of  severe  headache  suggests  a  spontaneous  subarachnoid  hemorrhage.  Turbid  fluid  (see  Fig.  25.59)  obtained  from  a  patient  with  headache  and  neck  stiffness  suggests  meningitis.
