Authors: Dahnert WF, Hamper UM, Eggleston JC, Walsh PC, Sanders RC.Title: Prostatic evaluation by transrectal sonography with histopathologic correlation: the echopenic appearance of early carcinoma.
Fifty-two patients with clinical stage A and B carcinomas of the prostate were
imaged by ultrasound (US) transrectally with a 5-MHz linear array transducer and
transabdominally with a 3-MHz sector scanner prior to radical prostatectomy. The
fresh specimens of 44 prostate glands were scanned in a water bath with a 5-MHz
linear array transducer in multiple planes. In all cases, histopathologic
correlation was obtained. Prostatic carcinoma presented as an echopenic lesion
in 54% of the specimens, as a slightly hypoechoic area in 22%, and could not be
identified in 24% because of its isoechoic characteristics. In contrast to many
previous reports, no instance of echogenic cancer was observed.
