Thanks to the widespread use of prostatic transrectal ultrasound (TRUS) scanning in uro-andrological practice today, there has been an increase in the incidental diagnosis of cystic lesions of the prostate; the mean rate is now 5 % (range 0.5–7.9 %) in patients with lower urinary tract symptoms (LUTS) . The clinical relevance of this finding is still under debate, but cysts have been associated with inflammation, obstruction of the seminal or urinary tract, as well as cancer. Making a correct differential diagnosis is therefore extremely important. During scanning, and also in the final ultrasound (US) report, prostatic cysts often tend to be largely ignored, neglecting to state both their identification and any characterization . In fact, there are no uniform, shared criteria for the final US report classification and description of their characteristics.
