Ultrasonography of cystic parotid lesions in HIV infection. Similarity of sonographic appearance with Sjögren's syndrome

Bilateral cystic parotid glands occur in some cases of human immunodeficiency virus (HIV) infection. This abnormality, which is associated with cervical adenopathy, can be defined by sonography in the superficial gland, as noted in three men. In retrospect, this parotid disease has similarity to the sonographic finding of Sjögren's syndrome, except for the finding of cervical adenopathy, an observation not previously appreciated.
