A case of AIDS-related hepatic Kaposi's sarcoma.
In Japan, Kaposi's sarcoma (KS) is a very rare neoplasm. However, it does occur as one of the complications in patients with acquired immunodeficiency syndrome (AIDS). AIDS-related KS commonly involves the skin, lymph nodes, and gastrointestinal tract. Hepatic KS is sometimes observed in AIDS patients at autopsy, but it is very rarely diagnosed during life. We report a case of hepatic KS in an AIDS patient, detected by ultrasonography (US), computed tomography (CT), and magnetic resonance imaging (MRI) during life and proven at autopsy. Abdominal US revealed multiple hyperechoic tumors along the portal vein. CT scan showed low density and delayed enhancement by contrast material. These tumors were revealed as a low intensity area on a T1-weighted image of MRI and as a high intensity area on T2-weighted and proton density images. US, CT scan, and MRI revealed characteristic findings of hepatic KS. These procedures are very useful for the diagnosis of hepatic KS. To our knowledge, this is the first report of hepatic KS in Japan.
