Introduction

: Primary Sjögren's Syndrome is anautoimmune disease that is characterized by an inflammatory process that primarily affects the exocrine glands. There is growing interest in the use of salivary gland ultrasound as a non-invasive tool for the diagnosis of primary Sjögren's Syndrome (pSS). Objective: To describe the ultrasound findings of salivary glands and glandular biopsy in patients with suspected primary Sjögren's Syndrome. Materials and methods: A cross-sectional observational study including adult patients with suspected pSS . In all cases, ultrasound and salivary gland biopsy were performed. Epidemiological, clinical, imaging (i.e. ultrasound) variables as well as pathology results of salivary gland biopsies were recorded. A descriptive analysis of the variables was carried out. Results: 23 patients with suspected pSS were included. The average age of the patients was 47.7±11.1 years, and 96.0% were female. All ultrasounds showed findings compatible with pSS, while 96% of the biopsies reported results compatible with pSS. Conclusion: In this group of patients, a high percentage of cases showed data compatible with pSS, both in the ultrasound and biopsy of the salivary glands.
