The Structures Forming Pedicle for Torsion are:

• Laterally – Infundibulopelvic ligament containing ovarian vessels, nerves and lymphatics
• Medially- Ovarian ligament, Medial end of Fallopian tube, Mesosalpinx
• Middle- Broad Ligament

Predisposing factors are: -

1. Trauma
2. Violent Physical movements
3. Contraction Of Pregnant Uterus
4. Intestinal peristalsis

Precipitating Factors:- Hemodynamic theory suggests that  slight axial rotation that leads to venous occlusion causes cyst to rotate with each arterial pulsation. It may get untwisted spontaneously or  few cases cyst may rupture and cause crisis situation.

• Varies with severity.
• In completely occluded cases, severe pain is the complaint.
• Lump may be feltper abdomen.
• Patient is in agony but general condtion is fair.

• Pelvic examination reveals that the mass is separate from the uterus.

Differential Diagnosis:

1. Disturbed Ectopic gestation
2. Acute Hydramnios
3. Perforating mole
4. Torsion of Fibroid
