Prostate cancer - unilateral PIRADS 4

Case contributed by Ian Bickle

Presentation

PSA 3.36. DRE benign. Are there any areas to target at biopsy?

Patient Data

Age: 70 years
Gender: Male

Prostate volume 82 mls.   PSA density 0.04ng/ml.
9 mm PIRADS 4 lesion in the left peripheral zone at the apex. 
Extensive BPH.
Normal seminal vesicles.  No pelvic nodes.  No bone lesions.
Sigmoid diverticulosis.

Case Discussion

A very convincing small PIRADS 4 focus (remember these are no different from PIRADS 5 in terms of imaging appearance only size).

If this lesion was more than 1.5 cm it would be a PIRADS 5.

It is surrounding by a completely normal peripheral zone.

As with the vast majority of the demographic undergoing prostate MRI, there is considerable BPH.
