“…[1][2][3][4]6,7 Sonographic features of infiltration of parotid malignant tumours were not found in this study and are seldom reported in other literature. CDFI may find parotid masses blood supply information, but the distribution in benign and malignant lesions had no significant difference and its value was limited, which was consistent with Bradley et al 8 and Schick et al 9 The potential limitations of the study were that the sample size was not large enough, some small nodules and large size masses without FNA or pathological results were not included, a few cases did not undergo ultrasound examination and were not included, and the clinical data, including history, speed of growth, pain, facial palsy and so on, were not enrolled, which may affect the study of the parotid gland masses.…”

“…Ultrasound plays an important role in the diagnosis of space-occupying lesions. Some studies [1][2][3][4] found that ultrasound was able to differentiate between benign and malignant parotid masses with high accuracy while other studies [5][6][7][8][9] presented opposing conclusions. The aim of this study was to assess the role of ultrasound in the evaluation of benignity and malignancy of parotid gland masses.…”

Objectives: This study aimed to investigate the value of ultrasound in the identification of benign and malignant parotid masses. Methods: Data of 189 patients with parotid gland masses undergoing ultrasound-guided fineneedle aspiration (FNA), core biopsy or surgery were reviewed retrospectively and the presumed sonographic diagnoses were compared with the histopathology. The sensitivity, specificity and accuracy of sonographic diagnoses were assessed and the sonographic characteristics of those lesions, including shape, margin, echogenicity, echotexture and vascularization, were studied. Results: Of the 189 patients, the final pathological diagnosis included 18 malignant tumours and 171 benign masses; the presumed sonographic diagnoses showed 165 cases as benign and probably benign masses (11 cases were confirmed malignant, 154 cases benign) and 24 cases were diagnosed as probably malignant and malignant masses (7 cases were confirmed malignant, 17 cases benign). The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of ultrasound for the diagnosis of parotid gland masses were 38.9%, 90.1%, 29.2%, 93.3% and 85.2%, respectively, and accuracy for malignant masses was 20%. The sonographic characteristics of parotid masses between benign and malignant lesions had no significant differences. The parotid gland masses in this study included pleomorphic adenoma, Warthin's tumour, retention cyst, haemangiomas, chronic granuloma, lymphoma, fibrolipoma, abscess, basal cell adenoma, oncocytoma, lymphatic tuberculosis, myoepithelioma, neurilemmoma, mucoepidermoid carcinoma, adenoid cystic carcinoma, alveolar soft part sarcoma and retinal blastoma (metastasis). Conclusions: It is challenging to use sonography for differentiating between benign and malignant parotid gland masses. To make a definite diagnosis, ultrasound-guided FNA or core biopsy is advocated.

“…Pleomorphic adenoma was the most common benign neoplasm found in present study correlating with the other study. 14 This study also showed the use of colour Doppler is assessment for the lesions of the salivary glands. The Doppler showed patterns of colour flow such as increased vascularity in cases of sailadenitis.…”

Background: Lesions of salivary gland are very commonly encountered in clinical practice. Only by Clinical examination alone it is difficult to differentiate between them and know its exact cause and etiology. It would definitely benefit the patient as well as the doctor if they could get an idea of the exact type of lesion affecting the salivary gland. Hence, this study was undertaken to demonstrate as how high resolution ultrasound imaging and use of colour Doppler can be useful in evaluation of salivary gland lesions.Methods: Duration of study was1yearwith sample size of 30 patients. This study has been conducted in the department of Radiodiagnosis JNMC, Sawangi, Wardha all cases irrespective of age and sex referred to the department were evaluated. Aloka Prosound Alpha 7 USG machine with a high resolution probe linear transducer was used. The lesions were evaluated by high resolution real time ultrasound and colour Doppler.Results: Most of the patients were in the age group 41-50years and had male preponderance. Most presented with unilateral swelling which was tender and firm in consistency. Amongst the study group saladenitis was most frequent finding followed by pleomorphic adenoma and carcinoma. Pleomorphic adenoma was most common neoplasm having predilection for the parotid gland. Saladenitis was most common in submandibular gland. The commonest histopathological finding was pleomorphic adenoma.Conclusions: The study concludes that High resolution ultrasound can differentiate various salivary gland lesions. Addition with colour Doppler ultrasound can increase its diagnostic accuracy. High resolution ultrasound with colour Doppler sonography should be first line of imaging modality in suspected cases of salivary gland lesions.

“…However, Schick et al (72) report that high vascularization and high systolic peak flow velocity should raise the suspicion of malignancy. On the other hand, Bradley et al (97) conclude that tumors demonstrating an increased intratumoral vascular resistance index have an increased risk of malignancy. The presence of metastatic-appearing lymph nodes accompanying a tumor in the salivary gland strongly suggests a malignancy (Fig 28).…”
