CASE HISTORY / CLINIC:
Patient with very painful swelling in the parotid gland.
Discharge of a yellowish secretion from the left Stensen's duct upon massaging the gland. Very poor general condition, no fieber.


FINDINGS:
The T2-weighted image (left) reveals an enlarged and hyperdense left parotid gland. Some areas demonstrate a high hyperdensity, typical of cystic dilitations of the duct system.
The parotid gland appears generally enlarged and a bit hyperdense in the fat saturation T2-weighted image after contrast administration. Demonstration of a hyperdense central area in the superficial lobe due to strong contrast-enhancement. Some small-sized intra-parotid lymph nodes are also demonstrated.


DIAGNOSIS:
Sialadenitis


DIFFERENTIAL DIAGNOSIS:
Benign and malignant mass lesions of the parotid gland.
