Renal amoebic abscess detected on grey-scale ultrasonography. A case report.

Ultrasound scanning performed on a patient to exclude a liver abscess was negative, but demonstrated a fluid-filled lesion situated at the lower pole of the right kidney. This was confirmed on excretory urography and angiography, and aspiration produced typical amoebic pus. THe evidence for this diagnosis and the probably route of infection are discussed. The literature on renal amoebiasis is reviewed.
