Objective:
The purpose of this series is to describe the sonographic features of isolated torsion of the fallopian tube.
Methods:
Sonography was performed in 4 women with acute lower abdominal pain.
Results:
The uterus and ovaries were normal in the 4 women. The ipsilateral fallopian tube was distended with fluid. A round mass was seen close to the tube. A sonographic whirlpool sign was seen on rocking movement of the probe over the mass. Ipsilateral torsion of the fallopian tube was confirmed at surgery in all of them.
Conclusion:
The sonographic whirlpool sign is the specific sign of tubal torsion.

Toroids
When connected to a supply, the magnetic field generated in the toroid has field lines circular and concentric to its axis. Conventionally, the direction of this magnetic field is expressed using the right-hand rule. If the fingers of the right hand curl in the current direction, the thumb points in the...
