Parotid abscess secondary to brucellosis in a patient with primary Sjögren's syndrome.

Swelling in the salivary glands, particularly parotid glands, is observed in approximately one third of Sjögren's syndrome patients. However, such patients should be assessed in terms of causes such as malignancies, infections, amyloidosis, sarcoidosis, and other autoimmune diseases when parotid gland swelling is noted. It should be considered that the incidence of lymphoma increases in Sjögren's syndrome.

Diffusion-weighted MR imaging of thyroid nodules.

Introduction: The purpose of our study was to determine the diagnostic role of diffusion-weighted imaging (DWI) in the differentiating of malignant and benign thyroid nodules by using fine needle aspiration biopsy cytology criteria as a reference standard.
