Five new cases of heterotopic visualization of the gallbladder with diatrizoate are described. Repeat studies were performed in 3 of these cases and the phenomenon was shown to recur.
Using sodium diatrizoate there was no heterotopic opacification of the gallbladder 24 hours after double dose intravenous pyelography in 101 normal cases; it did not occur after 3 hours in 97 other normal cases. It also did not result following 8 normal infusion pyelographies.
As a general rule, when this phenomenon has occurred with the diatrizoates, renal dysfunction with delayed excretion of contrast material has been shown to exist and creatinine and blood urea nitrogen values have been elevated.
