干燥综合征的涎腺超声表现及临床意义

The Salivary Gland Ultrasonic Manifestation and Clinical Significance of Sjgren Syndrome

干燥综合征(SS)是一种慢性自身免疫性疾病,通常累及泪腺、唾液腺,临床表现为口干、眼干。涎腺受累常导致口干燥症、腮腺肿大,涎腺的客观检查对SS的诊断有重要意义。涎腺超声(SGU)的实质回声不均匀、多发低回声结节改变是SS患者的特征性表现。SGU对临床诊断的价值等于或优于腮腺造影、腮腺核素及唇腺活检等检查,并且有无创、经济、简便易行等优势,越来越多地被风湿病学家和超声科专家所关注。

Sjgren syndrome( SS) is a chronic autoimmune disease,often involving lacrimal gland and salivary gland,with the symptoms of dry eyes and dry mouths. Salivary gland damage can cause xerostomia,parotid enlargement,and the objective examination of salivary gland is very important for the diagnosis of SS.The parenchymal inhomogeneity and multiple hypoechogenic areas are the salivary gland ultrasound( SGU)features of SS patients. The clinical diagnosis value of SGU is the same or prior to the parotid sialography,scintigraphic and the labial gland biopsy,and SGU has the advantages of non-invasive,economic. simple and easy. SGU is getting more attention from rheumatologists and ultrasonic specialists.
