Welcome to icliniq.com.
The MRI scan of the prostate (attachment removed to protect patient identity) shows a grossly enlarged prostate which is indenting the lumen of the urinary bladder and which you are probably aware of. Further, the median lobe of the prostate is showing hypertrophy and projecting into the base of the urinary bladder area.
The volume of the urinary bladder is significantly decreased and I can see that there is circumferential wall thickening of the urinary bladder. This can mean that the enlarged prostate has been causing bladder outlet obstruction and that is leading to retention of urine and infection. There are no obvious features of prostate cancer on T2 and diffusion images. There is no area of strikingly abnormal enhancement.
I would interpret the findings to be due to gross enlargement of the prostate and causing bladder outlet obstruction causing urinary bladder wall infection.
