sarcoidosis of the parotid glands

A rare case

of sarcoidosis involving primarily the parotid glands: US and MRI correlation. Axial T2W image showing multiple hyperintense lesions within both parotid glands.

A rare case

of sarcoidosis involving primarily the parotid glands: US and MRI correlation. Coronal T2W image showing the same parotid lesions and prominent lymph nodes in the posterior triangles.

A rare case

of sarcoidosis involving primarily the parotid glands: US and MRI correlation. Axial T2W image with fat suppression showing multiple high signal nodules in both parotid glands.

A rare case

of sarcoidosis involving primarily the parotid glands: US and MRI correlation. Axial, unenhanced T1W image showing multiple slightly hypointense nodules in both parotids, possibly representing solid rather than cystic components.

A rare case

of sarcoidosis involving primarily the parotid glands: US and MRI correlation. Axial T1W+C image showing diffuse enhancement of the parotid glands. The nodules do not enhance.

A rare case

of sarcoidosis involving primarily the parotid glands: US and MRI correlation. Coronal T1W+C image showing non enhancing nodules in the parotid glands.

A rare case

of sarcoidosis involving primarily the parotid glands: US and MRI correlation. Grey-scale ultrasound of the right parotid gland showing multiple hypoechoic nodules (granulomata and a few intraparotid lymph nodes).

A rare case

of sarcoidosis involving primarily the parotid glands: US and MRI correlation. Color Doppler ultrasound of the right parotid gland showing increased vascularity. Some of the nodules demonstrate hilar vessels (in keeping with intraparotid lymph nodes).

A rare case

of sarcoidosis involving primarily the parotid glands: US and MRI correlation. Gray-scale ultrasound of the left parotid gland. Some of hypoechoic nodules contain calcium deposits (arrow).

A rare case

of sarcoidosis involving primarily the parotid glands: US and MRI correlation. Color Doppler Ultrasound of the left parotid gland showing increased parenchymal vascularity. Some of the nodules show hilar vascularity consistent with intraparotid lymph nodes.
