Definition[Bearbeiten]
The appendix testis or Morgagni hydatid is a small appendage of the testis that is a remnant of the embryonic paramesonephric duct (Müller duct).
Anatomy[Bearbeiten]
The appendix testis is located at the upper pole of the testis covered by the tunica vaginalis testis. It is present in about 80-90% of all men, is oval in shape and normally has a maximum size of 5-6 mm in adults.
Clinic[Bearbeiten]
The appendix testis can be the starting point for hydatid torsion, which must be considered as a differential diagnosis of testicular torsion.
