<<Priapism is a common complication of sickle cell anemia. We report a little known sequela of priapism: painless megalophallus, with significant penile enlargement. The patient had had an intense episode of priapism 9 years previously and his penis remained enlarged. Blood oxygen level-dependent magnetic resonance imaging revealed enlarged, hypoxic corpora cavernosa. Megalophallus probably resulted from permanent loss of elasticity of the tunica albuginea due to severe engorgement during the episode of priapism. This sequela needs to be recognized by physicians because no intervention is necessary and sexual function seems to remain intact.>>
From Big Girtha’s link I’m guessing the loss of elasticity means the flaccid size becomes erect size - and the erect size has increased.
Also like Mgus asked what does having hypoxic cc’s mean? If sexual function remains intact is hypoxia that bad?
And again megalophallus pics are as rare as rocking horse droppings!
