AIM: The parotid gland is a rare site of @entity370 (6% of all cases). The role of state-of-the-art ultrasound techniques in the diagnostic assessment of parotid @entity370 ( @entity31489 ) is presented. @entity1 AND METHODS: Four @entity1 (three male, one female; aged 31-42 years) with inconclusive @entity4 associated with @entity221 and @entity1596 were referred for diagnostic assessment by the ENT outpatient service over a 1 year period. High-resolution ultrasound (US) was performed using the SONOLINE Elegra system with a 7.5-MHz wide-band transducer and various, special US techniques (tissue harmonic imaging, photopic imaging, color-coded duplex US, and power Doppler). Diagnoses were confirmed in all cases by puncture and histology. RESULTS: Two @entity1 with typical lung findings (stage I and II @entity370 ) and two @entity1 without known @entity370 showed an inhomogeneous nodular appearance of the clinically enlarged salivary glands at US. Duplex US demonstrated hypervascularization in three cases and moderate, inhomogeneous vascularization in one. In comparison to plain B-mode scanning, optimal visualization of the hypodense, nodular, structural changes was achieved using contrast-enhancing techniques. All @entity1 underwent US-guided puncture for determining the etiology of @entity8174 . Histology demonstrated granulomatous epitheloid cell @entity32 . CONCLUSION: An inhomogeneous nodular appearance of the parenchyma of enlarged parotid glands with areas of hypervascularization, which is optimally depicted by state-of-the-art US techniques, should suggest @entity31489 as a possible differential diagnosis.
