Ten MHz high-resolution sonography with direct probe scanning and probe scanning with a low-attenuating ultrasonic acoustic coupler were compared in 30 patients with pleomorphic adenoma. 1) The margins of the adenoma were clearly delineated with probe scanning with the coupler in all cases. 2) Decreased internal echogenicity was obtained in 73.3% of the pleomorphic adenomas, while internal echogenicity was the same in 26.7%.3) Large cystic degenerations were demonstrated in 26.7% of the adenomas and small cystic degenerations in 26.7%. 4) Calcifications (small areas of high echogenicity) were disclosed in 43.3% of the adenomas. 5) Enhanced posterior echoes were demonstrated in all cases. 6) Decreased lateral shadows were demonstrated in those with decreased internal echogenicity (73.3%), while 26.7% of those with the same internal echogenicity showed no change in the lateral shadow.
