Paratubal and tubal abnormalities.

The fallopian tubes are the essential genital ducts that convey the female sex cells for fertilization. They are differentiated and detectable early in fetal life. There are numerous paratubal and tubal abnormalities that can occur at any point in the female life. Some of these are rare but may initiate significant morbidity and/or manifest as life-threatening clinical problems. A comprehensive understanding of symptoms, diagnosis, optimal imaging modalities, and medical and surgical management is vital to identify the best treatment option. The clinical entities described in this article include torsion, hydatids of Morgagni, paraovarian cysts, infections including tuboovarian abscess/pyosalpinx and salpingitis isthmic nodosa, ectopic pregnancy, tumors, and genetic disorders.
