Facial involvement of brown tumor is rare and usually involves the mandible. Giant cell tumor ( GCT) is an expansile osteolytic bone tumor which is very similar in clinical, radiological and(More)
OBJECTIVES Pre-operative differentiation of salivary gland neoplasms is of great importance. This study was designed to evaluate the use of dynamic contrast-enhanced MRI (DCE-MRI) for differentiation between malignant, Warthin and benign non-Warthin (BNW) neoplasms of major salivary glands. METHODS 46 major salivary gland tumours (SGTs) underwent(More)
