Abstract
Human Immunodeficiency Virus (HIV) infection may involve the salivary glands, although the sonographic appearances are not well described. In this article, we describe three patients with known HIV infection who presented with salivary gland enlargement, associated neck lymphadenopathy, and no other symptoms or signs of underlying Sjögren's syndrome. In each of the patients, ultrasound examination demonstrated salivary gland appearances identical to those described in Sjögren's syndrome with lymphadenopathy also present in the neck. HIV infection may cause sonographic appearances identical to Sjögren's syndrome within the salivary glands and should be considered in the differential diagnosis if such features are observed.
