[Ultrasound findings in HIV patients].

A wide range of abnormal findings can be seen at abdominal ultrasonography in patients with HIV infection. The most frequent findings, hepatomegaly, splenomegaly, and enlarged lymph nodes, are nonspecific, however. Increased echogenicity or focal lesions of parenchymal organs, dilated bile ducts, nephromegaly, gut wall thickening or abscesses are uncommon findings. If there is clinical suspicion for a treatable disease, abnormalities seen on ultrasound examination of HIV-infected patients need to be confirmed by guided biopsy.
