Fig. 3-256 Transverse and longitudinal
sonograms of the prostate of 6-
year-old male Rottweiler with a
history of stranguria and chronic
urolithiasis. The prostate is enlarged
but normally shaped. The architecture
is uniform with multiple small
hypoechoic and hyperechoic
regions. This is indicative of hyperplasia.
Diagnosis: Prostatic hyperplasia.
Fig. 3-257 Transverse sonograms of
the prostate of an 11-year-old
male Standard Poodle with a
history of chronic hematuria and
prostatomegaly. The prostate is
enlarged and contains multiple small
hyperechoic foci. These do not form
shadows and therefore may not represent
mineral. This is most likely due
to prostatic neoplasia. Diagnosis:
Prostatic carcinoma.
Prostatic hyperplasia usually produces a uniformly textured enlarged prostate. 57,877,878
The echo intensity of the prostate is normal. Small hypoechoic or anechoic cysts may be
identified (Fig. 3-256).
Prostatitis and prostatic carcinoma can create single or multiple foci of increased echo
intensity (Fig. 3-257). 877 Differentiation of these two conditions is difficult when based
