Morgagni Hydatide

The term Morgagni-Hydatide - from old Gr . ὑδατίς, hydatis (watery, containing water ) - describes two different anatomical structures as the remnants of 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 gang . The gait is created in the man, but then degenerates under the influence of the anti-Müllerian hormone . The appendix testis is a vesicle-shaped, sessile appendage that is located on the testicle next to the head of the epididymis . It represents the cranial end of Müller's duct, which migrated into the scrotum through the descent testis .

In women there are small, pedunculated, fluid-filled vesicles on the fimbrial funnel of the fallopian tube as a cystic expansion of Wolff's duct from 2 to 10 mm in size. Usually such hydatids are found incidentally during laparoscopy . Surgical removal makes sense if they are larger and there is a risk of stem rotation .

Diseases

Classification according to ICD-10
N44.1	Hydatid torsion in men
N83.5	Hydate torsion in women
ICD-10 online (WHO version 2019)

Mostly men are at risk of torsion of the hydatides, which rarely occurs in women. This interrupts the blood supply to the cyst. The symptoms of torsion of the testis appendix ( hydatid torsion ), sudden pain, correspond to those of testicular torsion , but are usually short-lived and less intense. Hydatid torsion occurs predominantly in children and adolescents, but can occur at any age. After the diagnosis has been confirmed or a testicular torsion has been ruled out by ultrasound, the treatment is usually primarily conservative with pain relievers or anti-inflammatory drugs (e.g. ibuprofen), physical restraint and local cooling. In cases of pain that is difficult to control or persistent, the hydatids are surgically removed. Some sources generally give priority to the surgical treatment of this acute event.
