A patient of migraine-like headache with amnesia, pleocytosis and transient hypoperfusion of cerebral blood flow.
Pseudomigraine with pleocytosis (PMP) is an uncommon disease in Japan. The diagnostic criteria include at least one episode of transient neurological deficit accompanied or followed by migraine-like severe headache, cerebrospinal fluid (CSF) lymphocytosis, and normal neuroimaging. Both the etiology and the pathophysiology of PMP is not yet well defined. We report a 40-year-old man with a PMP-like syndrome. He came to our clinic because of severe throbbing headache and amnesia, and the examination showed CSF lymphocytosis of 23/mm3, a transient decrease of cerebral blood flow in the left thalamus. All the symptoms were completely resolved within 2 months.
