Abstract: This section of the chapter provides comprehensive description of MR features for normal anatomy, developmental growth, and related anomalies of the scrotum. The normal scrotum is divided by a midline septum called raphe, and each half of the scrotum contains a testis, the epididymis, and the scrotal portion of the spermatic cord. A normal testis has homogeneous texture of high signal intensity on fat-suppressed T2-weighted image, and covered with the tunica albuginea and the visceral layer of tunica vaginalis which are seen as a thin stripe of low signal intensity. The epididymis, which overlies the superolateral aspect of the testis, shows intermediate signal intensity lower than that of the testis on FST2-weighted image. Fibrous septa dividing seminiferous lobules are seen as low signal intensity and prominent on heavily T2-weighted image, especially in patients with infertility. Also described are other MR features found in abnormal anatomy such as cryptorchidism, inguinoscrotal hernia, hydrocele, bell clapper deformity, varicocele, etc.
