SIN is associated with infertility and ectopic pregnancy,[1] and may present as either.
It is characterized by nodular thickening of the tunica muscularis of the narrow (isthmic) portion of the Fallopian tube. In severe cases, it leads to complete obliteration of the tubal lumen. It is uncommonly bilateral.[2]
It is diagnosed with hysterosalpingography.
