Fig. 5.2. Normal grey-scale ultrasound anatomy. Axial scan on the dorsal aspect of the penis showing the paired corpora cavernosa (CC), the corpus spongiosum (CS) and the penile septum (open arrows). The tunica albuginea (arrowheads) appears as a thin echogenic line surrounding the penile bodies. The Buck s fascia is visualized near the corpus spongiosum (curved arrows) while in the remaining portions is stuck on the tunica albuginea. The penile septum appears as an echogenic structure with back attenuation...
