Abstract

A 31-year-old woman was admitted to the hospital after several episodes of transient numbness in her fingers and dysarthria. No neurological symptoms and signs were observed in this patient on admission; however, blood tests revealed elevated amylase and immunoglobulin G levels, an increased erythrocyte sedimentation rate, and positive anti-Sjögren's-syndrome (SjS)-related antigen A antibodies. The cerebrospinal fluid examination revealed a slight increase in the cell count and protein content. Diffusion-weighted and fluid-attenuated inversion recovery images on magnetic resonance imaging showed high-signal-intensity lesions in the cerebral white matter and basal ganglia supplied by the left middle cerebral artery. A part of the lesions was enhanced by the administration of gadolinium contrast medium. Magnetic resonance angiography suggested stenosis in the left anterior, middle, and posterior cerebral arteries. The patient was thus diagnosed with acute cerebral infarction and was then treated with argatroban, edaravone, and clopidogrel. Furthermore, Schirmer's test, sialography, and salivary gland biopsy results led to the diagnosis of SjS. A nerve conduction study suggested concomitant mild polyneuritis or mononeuritis multiplex. Collectively, we speculate that cerebral arterial stenosis associated with SjS leads to transient ischemic attack-like episodes, transient neurological symptoms and signs, and cerebral infarction.
