Ductuli aberrantes
（重定向自Ductus aberrans）
Ductuli Aberrantes.—A long narrow tube, the ductulus aberrans inferior (vas aberrans of Haller), is occasionally found connected with the lower part of the canal of the epididymis, or with the commencement of the ductus deferens.
Its length varies from 3.5 to 35 cm., and it may become dilated toward its extremity; more commonly it retains the same diameter throughout.
