Parotid gland enlargement in HIV infection: clinical/imaging findings.
Parotid gland enlargement with or without facial paralysis may be the presenting clinical manifestation of AIDS. Submandibular involvement may occur as well. Failure to recognize this association may lead to inappropriate or unnecessary intervention in the investigation and treatment of the salivary gland enlargement. In this paper, we discuss the role of imaging techniques in the investigation of salivary gland enlargement, and identify the specific radiologic signs found in HIV infection. Demonstration of intraparotid or submandibular gland cysts with focal intraparotid mass lesion(s) on imaging may help to differentiate parotid gland enlargement due to HIV infection from the many other causes of parotid enlargement.
