title: [Pseudomigraine with transient neurological deficits and cerebrospinal fluid lymphocytosis].
abstract: BACKGROUND
  Pseudomigraine with temporary neurological symptoms and lymphocytic pleocytosis is a rare syndrome resolving within less than 3 months.
  
  
  METHODS
  A young 17-year-old woman without previous medical history was admitted to the hospital because of right motor weakness and language disturbances. The symptoms resolved in a few hours and were followed by severe left headaches with important vegetative signs. Several similar episodes were noted in the previous 10 days. Cranial MRI was normal. EEG showed important slowing of the cerebral electrogenesis. More than 250 lymphocytic cells were found at CSF analysis. Outcome was spontaneously favorable, without similar symptoms after 6-month follow-up.
  
  
  CONCLUSIONS
  Pseudomigraine with lymphocytic pleocytosis seems to be a particular syndrome of unknown origin. This is an elimination diagnosis, generally with a benign course.
