[Adenomyomatosis and cholesterol polyps of the gallbladder. A comparison of radiological and sonographic diagnosis].

To evaluate the accuracy of ultrasonic methods in diagnosing hyperplastic cholecystoses we performed sonography on 31 patients in whom adenomyomatosis of cholesterol polyps of the gall bladder had been diagnosed radiologically. Despite recent improvements in the image quality of ultrasound machines the ultrasonic method was no better in diagnosing cholesterol polyps than radiology and was inferior to radiology in diagnosing localized alterations of the gall bladder wall caused by adenomyomatosis. Thus for the latter radiology remains the method of choice.
