Different histological subtypes of parotid gland tumors: CT findings and diagnostic strategy

Synchronous unilateral parotid gland neoplasms of three different histological types.

A 67-year-old male with three synchronous tumors in the unilateral parotid gland is reported. Postoperative histological examinations confirmed the presence of three synchronous primary tumors, specifically pleomorphic adenoma, Warthin's tumor and salivary duct carcinoma, in the right parotid gland. To our knowledge, this is the first case report describing three different histological types in...

Comparison of three different techniques in parotid gland tumors using three dimensional conformal radiation therapy

Introduction: Background: Radiotherapy of parotid tumors is achieved by different radiotherapy techniques. So they deliver the dose to organs at risk such as contralateral parotid, temporal lobe & spinal cord. The consequences of high dose to OARs are xerostomia, Temporal lobe necrosis and loss of hearing. Purpose: The aim of this study was to compare different treatment tech...

The Diagnostic Value of B-Mode Sonography in Differentiation of Malignant and Benign Tumors of the Parotid Gland

Introduction: Different imaging modalities are used to evaluate salivary gland diseases, including tumors. Ultrasonography (US) is the preferred method on account of its ease of use, affordability, safety profile, and good tolerance among patients. The aim of this study was to evaluate the role of US in differentiating malignant from benign parotid tumors, in the context of previous controversy...

Diagnostic value of MR imaging of parotid gland tumors

Myoepithelioma of the parotid gland: CT imaging findings.

BACKGROUND AND PURPOSE Myoepitheliomas (MEs) are rare tumors of the parotid gland. Only a few case reports describing CT imaging features of ME have been published. The aim of this study was to describe and characterize the CT findings of MEs of the parotid gland. MATERIALS AND METHODS We retrospectively reviewed CT images of ME with pathologic correlation in 10 cases (4 men and 6 women; age ...
