In primary Sjögren's syndrome, it is extremely rare to observe subacute progressive lower-body parkinsonism with severe sensory hearing loss responsive to corticosteroid therapy. Sjögren's syndrome can cause heterogeneous symptoms; therefore, its diagnosis and introduction of treatment are prone to be delayed, particularly in cases without sicca symptoms or seronegative cases, which are more likely to be seen in patients with neurological complications. This report may help clinicians identify atypical early neurological symptoms in primary Sjögren's syndrome.
