The correlation of histopathological, microradiographic and ultrasonographic features in disease of the prostate gland.

The histopathological, microradiographic and ultrasonographic features of corresponding areas of 100 cadaveric prostates were examined and correlated statistically to investigate their relationship. Benign glands are seen to be related to reticular structure and mid-range echoes. Benign prostatic hyperplasia is related to microadenomatous structure and mid-range echoes, whilst cancer is related to amorphous structure and low echoes. A small number of cancers have irregular calcification present and these tumours are related to high echoes. The structure of the prostate gland is therefore related to its pathology and explains its ultrasound echogenicity.
