Ultrasonographic Features of the Fallopian Tubes

Fallopian tubes are not usually visible on a transvaginal pelvic scan unless pelvic fluid or pathological processes are present. Depending on the underlying pathological process, they may exhibit different wall thicknesses, grades of vascularization, and variable echogenicity. Recognizing the affected tube and assessing the possible underlying process is of primary importance in clinical practice, as pathological tubes may represent benign pathologies, oncological state, or life-threatening conditions requiring different treatment to preserve fertility. The aim of this pictorial review is to describe the main characteristics of the most common tubal pathologies to help clinicians recognize them.
