Hydatid of Morgagni
The term Morgagni hydatid denotes two different anatomical structures remaining remnants of the embryonic development in men and women. They are named after the Italian pathologist Giovanni Battista Morgagni ( 1682-1771 ).
In men, it is a functionless relic of the Müller- gangs. The course is created when man indeed, but then degenerated under the influence of anti -Müllerian hormone. The appendix testis is a vesicular, ungestieltes appendage, which is located on the testicle next to the head of the epididymis. It represents the cranial end of the Müller- gangs, which is mitgewandert by the descent of the testis into the scrotum.
In women, there are small pedunculated, fluid-filled blisters on Fimbrientichter of the fallopian tube as cystic expansion of the Wolffian transition from 2 to 10 mm size. Usually they are found such as hydatid incidental findings at laparoscopy. A surgical removal is only necessary if they are larger and there is danger of stem rotation.
Mostly in men is a risk of torsion of the hydatid, which hardly occurs in women. The blood supply to the cyst is interrupted. The symptoms of torsion of the appendix testis, sudden pain, similar to those of testicular torsion, but are usually short-lived and less intense. The Hydatid torsion occurs predominantly in childhood and adolescence, but can occur at any age. The treatment consists of surgical removal of the hydatid.
