Focal Lesion in Prostate
Differential Diagnoses: Prostate
(Left) TRUS image shows a
hypoechoic left peripheral
zone (PZ) lesion with
bulging of the left lateral
prostate contour &
thickening of the left
neurovascular bundle (NVB)
st. A smaller hypoechoic
lesion is in the right PZ .
(Right) Color Doppler shows
focal hypervascularity of the
left PZ lesion & mild
hypervascularity of the right
PZ lesion. Prostatectomy
pathology showed multifocal
cancer, including left PZ
Gleason 5+5 adenocarcinoma
with left extraprostatic
extension and NVB invasion.
Prostate Carcinoma (PCa)
Prostate Carcinoma (PCa)
(Left) TRUS image performed
during MR-US fusion biopsy
shows a hypoechoic target
(outlined in red) within the left
transition zone. Ruler shows
the planned biopsy tract.
Pathology showed Gleason
4+5 adenocarcinoma. (Right)
Transverse transabdominal
image demonstrates multiple,
small, shadowing, bright
reflectors ſt scattered
throughout the prostate
corresponding to
brachytherapy seeds.
Prostate Carcinoma (PCa)
Prostate Carcinoma (PCa)
(Left) TRUS image shows focal
hypoechogenicity in the left
peripheral zone ſt with mild
bulging of the contour st.
Periurethral and transition
zone calcifications are
present. (Right) Color Doppler
image shows focal
hypervascularity in this region
. Pathology from targeted
biopsies of this region showed
focal prostatitis.
