  • Figure 1
    T1WI with and without contrast medium - parotid sarcoidosis
     

    Axial, unenhanced T1W image showing multiple slightly hypointense nodules in both parotids, possibly representing solid rather than cystic components.

     
    Area of Interest: Salivary glands; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Inflammation;

    Axial T1W+C image showing diffuse enhancement of the parotid glands. The nodules do not enhance.

     
    Area of Interest: Salivary glands; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Inflammation;

    Coronal T1W+C image showing non enhancing nodules in the parotid glands.

     
    Area of Interest: Salivary glands; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Inflammation;
     
     
  • Figure 2
    T2WI - parotid sarcoidosis
     

    Axial T2W image showing multiple hyperintense lesions within both parotid glands.

     
    Area of Interest: Salivary glands; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Inflammation;

    Coronal T2W image showing the same parotid lesions and prominent lymph nodes in the posterior triangles.

     
    Area of Interest: Salivary glands; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Inflammation;

    Axial T2W image with fat suppression showing multiple high signal nodules in both parotid glands.

     
    Area of Interest: Salivary glands; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Inflammation;
     
     
  • Figure 3
    Ultrasound images - parotid sarcoidosis
     

    Grey-scale ultrasound of the right parotid gland showing multiple hypoechoic nodules (granulomata and a few intraparotid lymph nodes).

     
    Area of Interest: Salivary glands; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Inflammation;

    Color Doppler ultrasound of the right parotid gland showing increased vascularity. Some of the nodules demonstrate hilar vessels (in keeping with intraparotid lymph nodes).

     
    Area of Interest: Salivary glands; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Inflammation;
     
     
  • Figure 4
    Ultrasound- left parotid gland
     

    Gray-scale ultrasound of the left parotid gland. Some of hypoechoic nodules contain calcium deposits (arrow).

     
    Area of Interest: Salivary glands; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Inflammation;

    Color Doppler Ultrasound of the left parotid gland showing increased parenchymal vascularity. Some of the nodules show hilar vascularity consistent with intraparotid lymph nodes.
