Multimodality imaging in adnexal torsion

Abstract

Adnexal torsions are one among the causes of acute pelvic pain in females. Commonly occurring adnexal torsions are ovarian either involving the normal ovary with functional cysts or an associated mass. Fallopian tube torsions, torsions involving paraovarian, fimbrial cysts and subserosal fibroids are rare. Here we discuss the multimodality imaging approach for the diagnosis of adnexal torsion, its limitations and mimics.

Spectrums and Outcomes of Adnexal Torsion at Different Ages

“…In our study, 94 cases involved ovarian torsion, and 15 cases consisted of isolated tubal torsion. The tube often twists with the ovary; thus, isolated fallopian tube torsion is rare and has been reported to occur at a rate of 1 in 1.5 million in previous studies . In our data, isolated oviduct torsion was not uncommon and represented approximately 13.8% (15 of 109) of the total torsion cases, despite the majority of ovarian torsion.…”

“…The twist may involve the ovarian ligament and suspensory ligament, or it may twist around the Fallopian tube . We identified two types in adnexal torsion, which presented as ovarian torsion (with or without the fallopian tube) or isolated fallopian tubal torsion without distortion of the ovary.…”

Spectrum of magnetic resonance imaging findings in ovarian torsion

“…This evaluation could not be done because the majority of our cases were of non-viable (infarcted) ovaries due to the fact that our institute is a tertiary care hospital with many cases being referrals from other hospitals for complicated or undiagnosed cases. However, irrespective of ovarian viability, any ovarian torsion has to be surgically treated (detorsion or oophorectomy) [16].…”

Diagnostic performance of diffusion-weighted MRI in the diagnosis of ovarian torsion: comparison of torsed and nonaffected ovaries

“…The increased incidence of ovarian torsion in children and pregnant women has attracted attention [15][16][17]. This situation can be associated with increased ligament laxity in childhood and pregnancy [1,16].…”
