title: [NMR tomographic diagnosis with Gd-DTPA in HIV-associated diseases in the head-neck area].
abstract: In a prospective study 21 patients suffering from HIV-1 infection underwent MR imaging. The following tumours were found: eight Kaposi's sarcomas, four lymphomas, two squamous-cell carcinomas, and three cases of lymphoid hyperplasia. Furthermore, three cases with lymphoepithelial cysts and one case of inflammatory changes of the parotid glands were studied. Optimal diagnostic results were obtained by using T1- and T2-weighted sequences plain and Gd-DTPA enhanced. Different signal intensities enabled the differentiation of lesions such as inflammation, lymphomas and lymphoid hyperplasia. Besides clinical examination modalities, MR imaging proves to be an important tool in investigating solid, cystic or inflamed processes in HIV-positive patients in the head and neck area.
