Multicentric parotid cysts and cervical adenopathy in AIDS patients. A newly recognized entity: CT and MR manifestations.

Patients with AIDS or ARC may present with parotid gland enlargement either initially or during the course of their disease. Of nine such patients, eight had unilateral gland enlargement, and one had bilateral disease. CT and MR scanning revealed that all patients except one had bilateral multiple intraparotid cysts. In addition, four of the nine patients clinically had cervical adenopathy, while all patients had adenopathy on scanning. We believe that the association of parotid cysts and cervical adenopathy is another manifestation of AIDS or ARC and, when found on scanning, should alert the clinician to the probable underlying condition.
