Isolated torsion of the normal fallopian tube in premenarchial girls.

Torsion of the normal fallopian tube in premenarchial girls is a very rare clinical entity with only four reported instances in literature. The clinical presentation of this entity is indistinguishable from acute appendicitis, and correct preoperative diagnosis is never made. The cause of torsion of normal fallopian tubes remains unknown. The surgical procedure of choice is salpingectomy, with care being taken to isolate and occlude the vascular pedicle prior to detorsion.
