Benign lymphoepithelial parotid cysts and hyperplastic cervical adenopathy in AIDS-risk patients: a new CT appearance.

The contrast material-enhanced computed tomographic (CT) scans of 18 patients at risk for acquired immunodeficiency syndrome (AIDS) who had painless facial swelling were reviewed. All scans demonstrated parotid cysts and diffuse homogeneous cervical adenopathy. The cysts were bilateral in all but three cases. Eleven of 13 patients tested had antibodies to the human immunodeficiency virus (HIV), and two of the five untested patients later developed AIDS. The authors believe that the CT findings of multiple parotid cysts and cervical adenopathy suggest that the patient may be infected with the HIV virus, and the radiologist should alert the referring physician so that appropriate precautions and treatment may be initiated.
