title: Chronic parotitis with multiple calcifications: Clinical and sialendoscopic findings.
abstract: To characterize clinical, imaging, and sialendoscopy findings in patients with chronic parotitis and multiple parotid calcifications.
  
  
  
  Retrospective review.
  
  
  
  Clinical history, radiographic images and reports, lab tests, and operative reports were reviewed for adult patients with chronic parotitis and multiple parotid calcifications who underwent parotid sialendoscopy.
  
  
  
  Thirteen of 133 (10%) patients undergoing parotid sialendoscopy for chronic sialadenitis had more than one calcification in the region of the parotid gland. Seven patients (54%) were diagnosed with immune-mediated disease from autoimmune parotitis (positive Sjögren's antibodies or antinuclear antibodies) or human immunodeficiency virus (HIV) disease. The six patients (46%) who did not have an immune-mediated disorder had most calcifications located anterior or along the masseter muscle. Eight of 13 patients (61%) had at least one calculus found in the parotid duct on sialendoscopy. Four patients (38%) had multiple punctate calcifications within the parotid gland, all of whom had either autoimmune parotitis or HIV. None of the proximal or punctate parotid calcifications posterior to the masseter were visualized on sialendoscopy.
  
  
  
  Chronic parotitis in conjunction with multiple parotid calcifications is uncommon and was identified in 10% of our cohort. We contrast two classifications of parotid calcifications: 1) intraductal stones that cause recurrent duct obstruction and are often located within the main parotid duct along or anterior to the masseter and 2) punctate intraparenchymal parotid gland calcifications that are not visualized on sialendoscopy and may represent underlying inflammatory disease.
