Prostate Zonal Anatomy • Transition Zone: Surrounds the prostatic urethra. Enlargement of this zone results in Benign Prostatic Hyperplasia • Central Zone: Lies in the base of the prostate posterior to the transition zone and surrounds bilateral ejaculatory duct. Comprises 25% of the gland. • Anterior Fibromuscular Stroma: Small area situated on the anterior aspect of the prostate • Peripheral Zone: Located on the posterior and lateral aspect of the prostate. Comprises 70% of the gland. Almost all carcinoma arise from this area. Dr. Devpriyo Pal @drdevrad #Prostate #Zonal #Anatomy #radiology #urology
