Cowper's glands and ducts in urethrography

Opacification of both Cowper's glands and ducts is a rare finding in urethroqraphv.' Its demonstration almost always indicates an abnormality in the posterior urethra or posterior aspect of the bulbous urethra. Conversely, its visualisation may be a diagnostic pitfall, and may lead to misinterpretation. We present a case delineating both Cowper's glands and ducts, to illustrate its anatomy so as to help differentiate it from pathological conditions.
