Ovarian torsion: CT and MR imaging appearances.

Abstract

Three findings (a, b, and d) seem to be diagnostic of the twisted adnexal tumor and may facilitate prompt surgical intervention at examination with MR imaging or CT.

Coexistence of Mature Cystic Teratoma and Endometrioma in an Ovarian Cyst

“…MCT is usually asymptomatic and doesn't have any specific symptoms. MCT can be associated with acute complications including torsion, rupture, infection or haemolytic anaemia [6]. Malignant transformation occurs in 1% of cases [7].…”

Preoperative Magnetic Resonance Imaging Diagnosis of Ovarian Torsion

“…Both ovarian enlargement and ascites had high sensitivities (100% and 93%, respectively) but low specificities (38% and 25%, respectively). Although twisted pedicle had a slightly low sensitivity (73%), this finding had a high speci- 4 Iran J Radiol. In Press(In Press):e14270.…”

“…Over the recent years, alternative techniques, such as computer tomography (CT) and magnetic resonance (MR) imaging, have become more frequently accepted in the diagnosis of ovarian torsion, particularly in subacute cases (4)(5)(6). Existing literature indicate that a number of different characteristic findings such as ovarian enlargement, twisted pedicle, ovarian hemorrhage, abnormal ovarian enhancement, ascites, deviation of uterus to the twisted side, and thickening of the fallopian tube are associated with ovarian torsion (6)(7)(8)(9).…”

Akut Abdomen

“…Yüksek yumuşak doku çözünürlüğü nedeni ile adneksal kitle-büyümüş over parankimini, dönmüş pedikülü ve kanama varlığını BT'den daha iyi gösterir. Akut kanama T1'de hiperintens, T2'de ise hipointens olarak görülür [17].…”
