They result from obstruction of a sublingual gland or adjacent minor salivary gland with resultant formation of a mucous retention cyst 1,5. Major salivary gland swelling involving both parotid glands and at times the submandibular glands, can be present. The salivary gland scan, also called parotid gland scintigraphy, is a non-invasive test.

Parotid gland parenchyma is subject to changes in its histological characteristics because of local or systemic conditions. Salivary gland ablation is a procedure performed by an interventional radiologist during which drugs are injected into the major salivary glands (submandibular, sublingual, and parotid glands), causing the salivary gland tissue to shrivel up and turn to scar tissue. 10. Fig. Once the branches of the facial nerve are identified, these cysts usually shell out easily. When a parotid-region mass is due to metastases to parotid nodes, computed tomography and magnetic resonance imaging can help to identify parotid cancer or another etiology as a cause. This is particularly true for the cervical region. This book reviews the sonographic features of the cervical structures, including the thyroid, parathyroids, salivary glands, lymph nodes, larynx and hypopharynx, and blood vessels. Imaging studies of the salivary glands are usually unnecessary for the assessment of small tumors within the parotid or submandibular gland. Pathologic states of the salivary glands include tumors (epithelial and non-epithelial), infections and inflammation, autoimmune diseases, vascular lesion, and non-salivary tumors. Link, Google Scholar; 56 Holliday RA, Cohen WA, Schinella RA, et al. Oncocytic neoplasms result from metabolically altered cells that accumulate abundant mitochondria within their cytoplasm to form oncocytes by the process of oncocytic metaplasia.

Radiographic features: Radiographic appearances largely depend on grade, making preoperative imaging important in planning and counseling. When imaging demonstrates multiple small nodules in the parotid gland with a large, solid, or cystic mass, the diagnosis of oncocytic neoplasia should be considered. Low grade parotid malignancy like adenoid cystic and mucoepidermoid carcinoma may be well demarcated, while in higher grade, more advanced parotid malignancy, the differential diagnosis is easy because of its invasive appearance on imaging. Pathology of the Salivary Glands. Salivary gland ablation is a procedure performed by an interventional radiologist during which drugs are injected into the major salivary glands (submandibular, sublingual, and parotid glands), causing the salivary gland tissue to shrivel up and turn to scar tissue.

This book provides a comprehensive and up-to-date overview of the role of diagnostic and interventional radiology in respect of liver tumors. Lymphoepithelial cysts (LECs) are associated with AIDS and represent the “classic” triad of head findings that occur in patients with human immunodeficiency virus (HIV) disease. SALIVARY GLAND RADIOLOGY. Introduction. Pathologic states of the salivary glands include tumors (epithelial and non-epithelial), infections and inflammation, autoimmune diseases, vascular lesion, and non-salivary tumors. Salivary gland tumours encompass 6% of all head and neck tumours, and 80% of them are seen in the parotid gland . 57. Lüers JC et al: Carcinoma ex pleomorphic adenoma of the parotid gland. The purpose of this study was to determine whether quantitative analysis of MR images of the parotid gland can differentiate patients with SS from normal subjects. Here is a complete reference on the fundamental science, treatment, and management of salivary gland disorders. Punctate calcifications were scattered within the parotid glands, but no intraductal stones were present. A broad spectrum of pathological conditions can affect the parotid glands. The most important factors in diagnosing cystic neck masses are a thorough history and physical, as the clinical presentation … Cystic lesions involving the salivary glands are mostly reported to be cystic neoplasms. Warthin tumorsare the second most common benign salivary gland tumor, accounting for 10% of parotid tumors. The indications for enrolling a patient at a given point in a series of diagnostic procedures are interpreted differently. One of the most striking examples is the use of sialography.

Salivary glands are quite susceptible to sarcoid [3]. A broad spectrum of pathological conditions can affect the parotid glands. The purpose of this study was to review our experience using conventional MR imaging of the neck in the evaluation of parotid tumors and to evaluate which MR imaging findings are best able to predict malignant histology.

We analyzed salivary blood flow (SBF) kinetics of 22 healthy parotid glands from 11 volunteers and 28 parotid glands from 14 SS patients using 3T pseudo-continuous ASL imaging. The parotid glands are the largest of all salivary glands, each weighing approximately 15-30 g. 1 Each parotid gland is positioned in the parotid space, which is bordered anteriorly by the mandibular ramus and masticator space, posteriorly by the mastoid tip, medially by the styloid process and parapharyngeal space, and laterally by the subcutaneous tissues. This book also serves as a preparation resource for recertification exams in radiology. In general, the ratio of benign to malignant tumors is proportional to the gland size; i.e. [] Few examples include pleomorphic adenoma, warthin's tumor, mucoepidermoid carcinoma, low grade papillary cystadenocarcinoma, and metastatic squamous cell carcinoma.
