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...
متن کاملDynamic Contrast Magnetic Resonance Imaging (DCE-MRI) and Diffusion Weighted MR Imaging (DWI) for Differentiation between Benign and Malignant Salivary Gland Tumors
Background: Salivary gland tumors form nearly 3% of head and neck tumors. Due to their large histological variety and vicinity to facial nerves, pre-operative diagnosis and differentiation of benign and malignant parotid tumors are a major challenge for radiologists. Objective: The majority of these tumors are benign; however, sometimes they tend to transform into a malignant form. Functional M...
متن کاملPertechnetate Scintigraphy for Warthin Tumors of the Parotid Gland: Comparison of Histopathological and Magnetic Resonance Imaging findings
Purpose: To examine the relationships between degrees of Tc pertechnetate (TcO4 ) uptake after acid stimulation and the tumor size as well as histopathological subtypes of Warthin tumor and to evaluate the diagnostic accuracy of TcO4 − scintigraphy and routine magnetic resonance (MR) imaging in differentiating Warthin and non-Warthin tumors of the parotid gland. Methods: We reviewed a total of ...
متن کاملWarthin tumor of the parotid gland: diagnostic value of MR imaging with histopathologic correlation.
BACKGROUND AND PURPOSE The purpose of our study was to describe the MR imaging appearance of Warthin tumors multiple MR imaging techniques and to interpret the difference in appearance from that of malignant parotid tumors. METHODS T1-weighted, T2-weighted, short inversion time inversion recovery, diffusion-weighted, and contrast-enhanced dynamic MR images of 19 Warthin tumors and 17 malignan...
متن کاملOncocytoma: the vanishing parotid mass.
Parotid gland oncocytoma is an uncommon, benign salivary neoplasm composed of mitochondria-rich oncocytes. The purpose of this study was to correlate MR imaging and histopathology of parotid gland oncocytomas and to define the features that may distinguish these neoplasms from other benign and malignant parotid gland tumors. The MR imaging features in 9 patients with a pathologic diagnosis of o...
