The Hydatid of Morgagni can refer to one of two closely related structures:

Hydatid can refer to:

In the male remnants of the mesonephric duct may be present as well and are also known as appendix of testis or hydatid of Morgagni.

There are many other conditions, such as testicular microlithiasis, epididymal cysts, and appendix testis (hydatid of Morgagni), which may be painful but are non-cancerous.

Another treatment that is also currently being looked into is laparoscropy hydatid liver surgery, whose efficacy is still controversial even though studies have suggested that it has clear benefits.

The appendix testis (or hydatid of Morgagni) is a vestigial remnant of the Müllerian duct, present on the upper pole of the testis and attached to the tunica vaginalis.

Occasionally a torsion of the hydatid of Morgagni can produce symptoms mimicking those created by a testicular torsion; a torsion of the hydatid, however, does not lead to any impairment of testicular function.

For E. vogeli, its hydatid cysts are large and are actually polycystic since the germinal membrane of the hydatid cyst actually proliferates both inward, to create septa that divide the hydatid into sections, and outward, to create new cysts.
