Self-limited recurrent multifocal neurological symptoms, headache, and cerebrospinal fluid lymphocytic pleocytosis: a benign syndrome with a predilection for young adult men.

Two young men, aged 34 and 30 years, developed transient recurrent multifocal neurological symptoms with associated severe headache over a 2-week period. Both had a lymphocytic pleocytosis in their cerebrospinal fluid. Cranial imaging studies were normal. All symptoms resolved without recurrence. Although the cause and pathogenesis are undefined, this self-limited benign neurological syndrome may be more common than previously recognized and has a predilection for young adult men.
