69-year-old male with history of high-volume Gleason 7 disease on the left. Pretreatment evaluation. PELVIS:PROSTATE:Prostate Size: The prostate measures 4.6 x 5.2 x 3.9 cm (cc by transverse by AP).Peripheral Zone: Within the midportion of the left posterior peripheral zone and extending towards but not reaching the apex is a area of confluent low T2 signal and restricted diffusion measuring 1.5 x 1.1 cm in the axial plane and 1.1 cm craniocaudal dimension. On the postcontrast images, the area of enhancement extends slightly beyond the abnormal T2 signal and there appears to be extension through the posterior lateral aspect of the capsule.Central Gland: Heterogeneous hyperplasia compatible with benign prostatic hypertrophy.Seminal Vesicles: Unremarkable.Extracapsular Extension: Suspicion for extracapsular extension on the posterolateral aspectBLADDER: No significant abnormality noted.LYMPH NODES: Scattered inguinal lymph nodes are within normal limits. No pelvic lymphadenopathy.BONES, SOFT TISSUES: No significant abnormality noted.OTHER: There is an unchanged simple cystic structure in the posterior aspect of the prostate posterior to the prostatic urethra, likely a utricle cyst.
1.Findings compatible with prostatic adenocarcinoma involving the posterior left peripheral zone with findings suspicious for extracapsular extension posterolaterally.
