The giant kidney worm (Dioctophyma renale) infection in man in Australia.
A 47-year-old, previously healthy farmer from Grafton, N.S.W. in Australia, developed loin pain and hematuria 2 months after minor trauma to his loin. A renal cyst was found by ultrasound and arteriography. At operation, a thick-walled cyst containing 800 ml of clotted blood was excised together with a small wedge of kidney. Ring-like structures measuring 70 X 45 mu were found in the fibrous cyst wall and in the surrounding fat. These birefringent double-walled "rings" with equally spaced radial striations were identified as the eggs of Dioctophyma renale.
