Methods: In this prospective clinical study, ultrasound scans were performed on 50 patients aged between 20–60years. Results: There were four main distinct ultrasound pathological patterns in the parotids, i.e. lymphocytic aggregations (LAs), lymphoepithelial cysts (LECs), fatty infiltration (FI) and lymphadenopathy only. There were additional subdivisions depending on the presence of echogenic foci and intraparotid lymphadenopathy. Of all these only two patterns were noticed in the present study. 46% cases showed LEC and only 2% cases showed FI.

Conclusions: In conclusion diagnostic ultrasound is the most appropriate imaging modality to investigate the parotid glands in HIV-positive patients.
