Background: Synchronous unilateral tumors in the parotid glands account for less than 5–10% of all salivary gland neoplasms. Mostly these are cystadenolymphomas, but tumors of different histological types can be found as well. In these cases it is often pleomorphic adenoma in combination with cystadenolymphoma. Ultrasound is the first choice imaging modality. Case report: We present two patients with two simultaneous tumors in a unilateral parotid gland. In each case, B-mode ultrasound showed two hypoechoic masses, one of which was predominantly cystic. The subsequent use of Virtual Touch Imaging Quantification (VTIQ) showed tumors of elastic tissue. After a parotidectomy, both cases were diagnosed with pleomorphic adenoma combined with cystadenolymphoma. Conclusion: The combination of B-mode ultrasound and VTIQ is an important diagnostic modality and may improve diagnostic accuracy to differentiate between benign and malignant lesions. Every clinician should be aware of the co-existence of different histological types of tumors in unilateral salivary glands.

“…Zengel et al (2017) using VTIQ showed that malignancies had much lower quality and the share wave velocity was higher than 6.8 m/s in comparison with benign lesions [41]. Using the same investigation, Liu et a. showed in their study that the coefficient of stiffness variability (CSV) which represents the ratio between the maximum and minimum stiffness values recorded with SWE is the strongest predictor of malignancy and allows parotid tumor differentiation between benignity and malignancy (p <0.0001) [27].…”

Ultrasonography techniques in the preoperative diagnosis of parotid gland tumors – an updated review of the literature

et al. 2020

Preoperative diagnosis of parotid tumors plays a crucial role in selecting and planning the surgical treatment. Ultrasound (US) with its modern techniques can contribute to the differential diagnosis of parotid tumors. This paper aims to achieve a comprehensive review of the ultrasound techniques used in the differential diagnosis of parotid tumors, based on the latest literature data. Considering that most parotid gland tumors are located in the superficial lobe, US is frequently the first imaging technique used for the diagnosis of parotid tumors. Sonoelastography can provide additional data on the elasticity of parotid tumors, but there is an overlap between malignant and benign parotid tumors parameters. Contrast-enhanced ultrasound adds value to conventional ultrasound and allows a more complete characterization of parotid tumors. Many authors have reported promising results using contrast-enhanced ultrasound in the differential diagnosis of parotid tumors. Multiparametric ultrasound with a careful and systematic approach usually allows an accurate differential diagnosis of parotid tumors.
