“…The two most prevalent salivary gland lesions, as reported in the literature, are Pleomorphic adenoma and Warthin's tumour [31,32]. Pleomorphic adenoma was the most frequent tumour comprising 54.2 % of all tumours and 80.3 % of the benign salivary gland tumours in the case series (256 cases) of Kamble RC et al [32]. In this study, also Pleomorphic adenoma (60 %) was the most frequent lesion, followed by Warthin's tumour (28 %).…”

Sonoelastography is a comparatively new and developing technology in the field of salivary gland imaging. Nevertheless, it has the potential to distinguish between various types of lesions by calculating the degree of strain-related deformation under the externally applied force. With this background, the present study was undertaken to evaluate the role of sonoelastography in characterising salivary gland lesions as benign or malignant. The aim: To evaluate and characterize salivary Gland lesions on the Gray scale and Colour doppler ultrasonography and sonoelastography and to correlate these findings with the clinico-pathological diagnosis. Methodology: This prospective cross-sectional study was conducted in the Department of Radiodiagnosis, Teerthanker Mahaveer Medical College & Research Centre, Moradabad (U.P.), from Aug 2021 to Nov 2022. All patients referred to the radiology department for imaging with clinical suspicion of having salivary gland lesions were enrolled in the study and evaluated on the SIEMENS ACUSON S3000 machine. Gray scale USG was done first to assess various morphological features of lesions, and then a Doppler assessment was done to determine vascularity within the lesion. Subsequently, real-time strain elastography (eSie touch) was performed to assess the tissue stiffness. The elastogram image of the detected lesions was evaluated using colour coding ranging from blue (soft) through green (intermediate/average hardness) and red (hard). After strain elastography, shear wave elastography of the lesion was also performed using Virtual Touch Quantification (VTQ) and Virtual Touch Imaging Quantification (VTIQ) software. The sonographic findings were correlated with histopathological diagnosis. The acquired data were subjected to statistical analysis using the software SPSS version 20. Sensitivity, specificity, PPV and NPV were calculated for conventional ultrasound techniques alone & in combination with elastography. Results: Out of the 50 salivary gland lesions included in the study, 44 (88 %) were benign, whereas 6 (12 %) were malignant on cytology. The age of the study population ranged from 16 to 75 years, with a mean age of 38.82 years. Pleomorphic adenoma (60 %) was the most frequent lesion, followed by Warthin's tumour (28 %). The Conventional USG showed 66.67 %, sensitivity, 52.27 %, specificity, 16.00 %, PPV, 92.00 % NPV and 54.00 % accuracy in differentiating benign from malignant lesions while USG- Elastography combined showed higher diagnostic performance with 83.33 %, sensitivity, 79.55 %, specificity, 35.71 % PPV, 97.22 % NPV and 80.00 %, accuracy. The specific cut-off scores for the sonoelastography score, eSie touch, VTQ, and VTIQ were also determined to diagnose a lesion as malignant or benign, and the difference was found to be statistically significant. Conclusions: Sonoelastography alone cannot be solely relied upon to distinguish between malignant & benign salivary gland abnormalities. However, it can be combined with conventional USG for better differentiation and characterization of these lesions

Introduction: Metastatic disease to the submandibular gland is a rare phenomenon with limited information available on related imaging findings. Case Presentation: We report a 59-year-old female who presented with a palpable nodule in the right submandibular gland 6 years after treatment for breast carcinoma. Ultrasound findings were concerning for distant metastatic disease from breast cancer recurrence. The histopathological analysis of the biopsied tissue confirmed infiltration of the right submandibular gland with an adenocarcinoma from a breast primary. Discussion: Metastatic spread to the major salivary glands is relatively uncommon with a predilection to the parotid gland owing to its extensive intraglandular lymphatic system. Conversely, metastasis to the submandibular gland, which lacks intraglandular lymph nodes, is rare. Ultrasound is the optimal first-line imaging modality to aid in the assessment of submandibular gland disease. Malignant lesions often appear hypoechoic with heterogenous internal architecture and ill-defined borders. However, some low-grade malignancies, can have apparently benign features particularly when smaller in size. Where a focal submandibular gland lesion is identified and neoplasm is suspected, the early use of ultrasound-guided core biopsy is recommended to improve diagnostic yield for histological assessment. Conclusion: While submandibular metastasis is rare, clinical assessment, sonographic findings and use of core needle biopsy aid in prompt diagnosis and management.

Objectives: The purpose of the present scoping review was to determine the contribution of ultrasound images in the diagnosis of inflammatory and obstructive diseases of the major salivary glands (MSGs). Methods: A search of studies of ultrasonographic assessments of human samples was performed in several electronic databases and grey literature up to July 2021. The extracted data were the examined MSG; the diagnostic value of ultrasound (sensibility, specificity, positive- and negative predictive value, accuracy); features of lesions, including number, echogenicity, echotexture, form, margins, size, posterior acoustic aspect, and location; and related clinical information, such as swelling, palpation, sensible to pain, salivation, lymph nodes, recurrence, duration, and causes. Results: After verifying the eligibility criteria, 90 articles focused on detecting inflammatory, and obstructive diseases of the MSG were gathered, with variable study designs and size samples. A wide variety of pathologies were assessed, including sialolitiasis (n = 45), acute sialadenitis (n = 30), chronic sialadenitis (n = 25), granulamatous diseases (n = 15), Kuttner’s tumor (n = 11), juvenile recurrent parotitis (n = 9), abscess (n = 7), post-radiotherapy sialadenitis (n = 6), sialadenosis (n = 9), abscess (n = 7), IgG4-related disease sialadenitis (n = 5), HIV-sialadenitis (n = 4), obstructive sialadenitis (n = 3), iodinated contrast-induced sialadenitis (n = 2), and pneumoparotitis (n = 1). Most studies were case reports or series of cases. Few studies exhibited data about the accuracy of ultrasound in detecting MSG diseases. Conclusions: The present scoping review concluded that ultrasound aspects of different MSG pathologies are similar but contribute to their differential diagnosis and can be considered as a valuable initial method for assessing the MSG of adults and children.
