Ultrasonography in Tropical Diseases

Summary Sonography is a useful imaging modality in the evaluation of tropical diseases. This article deals with the role of sonography in the diagnosis of various tropical diseases like tuberculosis, amoebiasis, and other parasitic infestations as seen in the tropics. The manifestations of tuberculosis in the liver, spleen, kidneys, retroperitoneum, serous cavities, and pelvic organs are described. The evolution and complications of amoebic abscess and hydatid disease are also discussed. The life cycle of various parasites and the sonographic detection of their manifestations are reviewed along with a brief account of the sonographic features of biliary asca-riasis, filariasis, leptospirosis, and malaria.
