Central nervous system (CNS) involvement of primary Sjogren’s syndrome (pSS) is a controversial issue. We present a case of pontine infarction presenting as a syncopal episode associated with pSS. A 46-year-old woman was admitted to CHA Bundang Medical Center owing to right-sided weakness and dysarthria. She had no medical illness or smoking history but had a syncopal episode for the first time 3 days before. Eye and mouth dryness were found after history taking. Laboratory test results were positive for antinuclear antibodies: anti SS-A (Ro) and anti SS-B (La) antibodies. Diffusion-weighted imaging revealed high signal intensities in the left pons. Magnetic resonance angiography revealed multifocal stenoses of the basilar and bilateral vertebral arteries. Previous research on pSS mainly focused on peripheral nervous system manifestations. In our case, the associations of the CNS lesion of vasculitis with ischemia and pSS are considered pathophysiological mechanisms.
