A prostatic cyst measuring 1.5*1.4 cm in size was present at the midline of the upper part of the bladder neck region (Fig. 2).
Coronal (A) and sagittal (B) pelvic MR images of the male patient showing a well-defined midline cyst arising from the prostatic base and herniating into the urinary bladder with no clear communication with the urethra. The cyst measured 1.6*1.3 cm and exhibited bright T2 signal intensity and hypo intense T1 signal intensity with peripheral wall enhancement characteristic of a cyst (red arrow).
