On the head of the epididymis is a small stalked appendage (sometimes duplicated). It is named the appendix of the epididymis (or pedunculated hydatid), and is usually regarded as a detached efferent duct.
This structure is derived from the Wolffian duct (Mesonephric Duct) as opposed to the appendix testis which is derived from the mullerian duct (Paramesonephric Duct) remnant.
