Abdominal ultrasound findings of disseminated tuberculosis in AIDS

The sonographic findings of 76 patients with tuberculosis and HIV infection are described. These findings were compared with a control group of 76 HIV-positive patients without associated pathology. Those patients with tuberculosis and positive HIV titers commonly (p = 0.05) showed retroperitoneal and mesenteric adenopathies with node diameters greater than 1.5 cm (n = 27), and multiple, splenic, hypoechoic nodules between 0.5 cm and 1 cm (n = 11). Additional findings include hepatic hyperechoic nodules (n = 1) and retroperitoneal abscess (n = 1). The combination of ultrasound features can help in the diagnosis of abdominal tuberculosis in HIV-positive patients with non-specific clinical infections.
