acute torsion of the adnexal structures

Synopsis

 Acute torsion of the adnexal structures is an uncommon event but is a surgical emergency.
 The severity of the symptoms varies widely and includes fever, nausea or vomiting, and abdominal pain.
 The correct diagnosis is rarely made preoperatively.
 The preoperative radiograph commonly shows a pelvic mass with a cystic or solid texture, often with thin internal septae, and may simu-late an ovarian mass.
 Because the sigmoid colon cushions and secures the left adnexa, the right adnexa is more often affected than the left.
 The Fallopian tube and ovary have usually undergone hemorrhagic necrosis by the time of the surgery, often with secondary calcification.
 As a result, the cause of the torsion is not clear in most cases.
