Methods: A total of 208 patients with parotid gland tumors and presurgical MRI were included. Our aim was to define typical magnetic resonance (MRI) findings in malignant and benign parotid tumours. A prophylactic selective neck dissection (levels I to III) should be performed for patients with high-stage (T3/T4) disease-free clinically high-grade tumors (i.e., high-grade mucoepidermoid carcinoma, carcinoma ex-pleomorphic adenoma, adenocarcinoma, squamous and undifferentiated carcinomas). The parotid glands are the most common place that salivary gland tumors happen. Mlika M, Kourda N, Zidi Y et al. The risk of lymphoma is increased in patients with Sjogren syndrome.

All procedures performed in studies involving human participants were in accordance with the ethical standards of the institutional and/or national research committee and with the 1964 Helsinki Declaration and its later amendments or comparable ethical standards. Although high-grade malignancies of the parotid gland usually have poorly defined margins, low signal intensity on T2-weighted images and invasion of surrounding structures, tumour margins, homogeneity, and signal intensity are not discriminative factors for correctly predicting benign or malignant tumours [12]. Bethesda, MD 20894, Web Policies The sensitivity, specificity, and accuracy of US in differentiation of malignant from benign lesions in the parotid gland were 60, 95.2, and 90.3%, respectively.

Cystic lesions observed in parotid glands are relatively rare and comprise 2-5% of all parotid primaries. Intraoperative tumor spillage carries with it an increased rate of recurrence over a prolonged period of time, and so long-term follow-up is recommended in such cases. Parotid gland enlargement (also known as parotidomegaly) has a wide differential given the significant breadth of pathology that can affect the parotid gland. This content does not have an Arabic version. Tests and procedures used to diagnose a parotid tumor may include: Collecting a sample of tissue for testing. Data sets were created in three of these studies with MRI and in two with computed tomography (CT). Management of salivary glandcancer needs an interprofessional approach involving a team that consists of an otolaryngologist, a maxillofacial surgeon, a pathologist, and a radiologist. Comparative diagnostic imaging and pathological analysis of echo color/power Doppler and of magnetic resonance imaging. Surgeons can repair the facial nerve using nerves from other areas of the body or from artificial nerves. Yu Q, Wang A, Gu J, Li Q, Ning Y, Peng J, Lv F, Zhang X. Howlett DC, Kesse KW, Hughes DV, Sallomi DF. Preoperative tumor localization, differential diagnosis, and subsequentselection of appropriate treatment for parotid gland tumors is critical.However, the relative rarity of these tumors and the highly dispersed tissuetypes have left an unmet need for a subtle differential diagnosis of suchneoplastic lesions . Malignant parotid gland neoplasms; Monomorphic adenoma; Parotid gland tumor; Pleomorphic adenoma; Ultrasound. The parotid glands are two salivary glands that sit just in front of the ears. Radiographics. Typical findings of pleomorphic adenoma included hyperintensity on T2w images (p = 0.02), strong contrast enhancement (p < 0.001) and lobulated shape (p = 0.04). The pathologist tells the surgeon if the tumor is cancerous. If there are no complications, you will likely be able to return home the same day. This article reviews the key history and physical elements and adjunctive diagnostic tools available for working up parotid lesions.

Imaizumi A, Kuribayashi A, Okochi K, Ishii J, Sumi Y, Yoshino N, Kurabayashi T. Differentiation between superficial and deep lobe parotid tumors by magnetic resonance imaging: usefulness of the parotid duct criterion. 1: digastric muscle 2: main trunk of the facial nerve 3: cervical branch of the facial nerve 4: marginal mandibular branch of the facial nerve 5: great auricular nerve divided distally. 6. Receiver operating characteristic curves were constructed to determine the predictive values of echogenicity, heterogeneity, and vascularity on color Doppler. Cross-sectional imaging is not essential in straightforward benign tumors, but MRI scanning of a parotid tumor is useful in the assessment and delineation of anatomical structures, extension into the deep lobe, and relation to the facial nerve. The gender incidence is equal, and they are seen most often in patients in their sixth decade. The WHO histological classification of salivary gland tumors now includes over 40 variantsas well as tumor-like lesions (e.g., salivary gland cysts).

Polymorphous adenocarcinoma is increasingly recognized, particularly as a tumor of the minor salivary glands on the soft palate. The age of the patient helps narrow the differential diagnosis, with vascular and congenital lesions being more frequent in the 1st year of life, while solid tumors are more frequent in older children.
