2b - Answer: 64-year-old male presents with prostate cancer
HISTORY:
This 64-year-old male presents with prostate cancer.
PRIMARY FINDING:
PI-RADS II.
FINDINGS:
The prostate is 3.8cm in transverse dimension, 3cm in AP dimension and 4cm in craniocaudal dimension. Ill-defined non-mass-like hypointensity in transitional and peripheral zones with focal area slightly more hypointense at posterior right mid peripheral zone (PZp). Mild generalized hypointensity on the high b-value ADC map. No focal areas of restricted diffusion. The capsule is intact. Hypointense and moderate atrophy of the seminal vesicles probably due to chronic obstruction. Neurovascular bundle intact.
No lymphadenopathy in the visualized pelvis. No focal suspicious osseous lesions.
CONCLUSION:
1. Given the pathology results, the prostate cancer probably is infiltrative type or of lower Gleason grade since no discrete aggressive mass or focal area of restricted diffusion on MRI. Subcentimeter low signal, 7-8mm rounded area right PZ mid (PI-RADS 2). Note that in BI-RADS in breast imaging this would qualify as a PI-RADS 6 (e.g., BI-RADS 6 which equals known cancer).
2. No MRI evidence of regional metastasis.
