- Testicular and epididymal appendages
- Epididymal appendages
Testicular and epididymal appendages are remnants of embryonic ducts and are quite common, with one or more being present in ~70% of patients 1.
Gross anatomy
Four such appendages have been described:
-
testicular appendix (hydatid of Morgagni)
- it is a Müllerian duct remnant (paramesonephric duct)
-
epididymal appendix
- it is a Wolffian duct remnant (mesonephric duct)
-
vas aberrans (of Haller)
- superior or inferior group of aberrant vessels located in a fissure between the epididymis and testis 1
-
paradidymis (Giraldes organ)
- vestigial structure located on the distal portion of the spermatic cord 1
Radiographic features
Ultrasound
A testicular appendix may be seen between the testis and epididymis on normal sonography, in many instances. An epididymal appendix is attached to the head of the epididymis and may be seen during sonography in one or both testes. However, both vas aberrans and paradidymis are not usually seen during imaging.
