Case: Primary erectile dysfunction due to congenital isolated cavernous bodies

The finding of a complete penile corporal septum is a rare malformation in which the corpora cavernosa are completely isolated and function independently. Keogh was the first to reference this in 1989.1 Kolbenstvedt reported what was thought to be a source of error in pressure recordings or in intracavernous injection.2 Gorga, in 1991, described isolated cavernous bodies in a patient with erectile dysfunction (ED).3 This abnormality may be associated with corporal veno-occlusive dysfunction and hypoplastic cavernous arteries. It can be recognized incidentally during penile duplex ultrasound (DUS), when a vasoactive agent is injected into one corpus cavernosum, producing tumescence in one side while the contralateral corporal body remains flaccid, requiring a contralateral injection to obtain a complete erection
