Abstract
Background The usefulness of T2*-weighted (T2*W) imaging for the detection of adnexal torsion has yet to be determined. Purpose To assess the usefulness of T2*W imaging for detecting and differentiating adnexal torsion. Material and Methods Eight patients with eight ovaries with torsion and 44 patients with 72 ovaries without torsion were included in this study. All patients underwent 1.5-T magnetic resonance imaging (MRI) including T2*W images. The frequency and distribution of hypointensity on T2*W images were compared between ovaries with torsion and ovaries without torsion. Results Hypointensity on T2*W images was significantly more frequent in ovaries with torsion than in ovaries without torsion (75% vs. 36%; P < 0.05). Among patients with hypointensity on T2*W images, the frequency of diffuse hypointensity was significantly higher in ovaries with torsion than in ovaries without torsion (83% vs. 0%; P < 0.01); whereas the frequency of focal hypointensity was significantly lower in ovaries with torsion than in ovaries without torsion (17% vs. 100%; P < 0.01). Conclusion The presence and distribution of hypointensity on T2*W images may play a supplementary role in the detection of adnexal torsion.

Abstract
Fallopian tube torsion is a rare but important cause of acute pelvic pain in young adolescent girls. It is a surgical emergency treated with either detorsion or salpingectomy. The imaging findings can be nonspecific and challenging. However, an accurate early diagnosis is essential for prompt surgical treatment. Our objective was to review whether imaging findings can be specific enough to suggest the diagnosis of tubal torsion prospectively in the appropriate clinical setting. An Institutional Review Board-approved retrospective review of our imaging database from 2005 to 2012 revealed 10 surgically proven cases of fallopian tube torsion. All cases had sonography performed; 5 cases had additional multidetector computed tomography. All 10 patients (9-17 years) presented with acute pelvic pain. Sonographic findings included dilated tubular structures in 6 of 10 cases: adjacent to a normal ipsilateral ovary in 5 of 6 and adjacent to a benign ovarian teratoma in 1. In 4 cases, no dilated tube was identified; 3 of 4 had a cystic mass separate from the ovaries, and 1 had the imaging appearance of a multicystic ovary. Computed tomographic findings in the 5 cases that underwent multidetector computed tomography included a dilated tubular structure in 3 of 5; 2 of 5 had a cystic adnexal mass identified. Although rare, tubal torsion should be considered in female adolescents with acute pelvic pain. Sonography should be the first imaging choice. When a tubular structure or a midline cystic mass associated with a normal ipsilateral ovary is noted, tubal torsion should be considered in the differential diagnosis.

Abstract
PURPOSE We undertook this study to evaluate the need for diffusion-weighted (DW) magnetic resonance (MR) imaging in detecting hemorrhagic infarction following ovarian torsion. METHODS The study included 14 consecutive patients aged 12 to 74 years (average age, 36 years) with surgical confirmation of ovarian torsion who underwent 1.5-tesla MR imaging. Pathologically, hemorrhagic infarction was found in 7 patients. We retrospectively reviewed signal intensity on T1-, T2-, and diffusion-weighted images and apparent diffusion coefficients (ADCs) in swollen ovarian stroma. RESULTS Fallopian tube thickening was seen in all patients. In patients with ovarian cystic lesion, maximum cyst wall thickness was significantly higher in patients with hemorrhagic infarction (mean, 13.5 ± 4.1 mm) than those without (mean, 5.0 ± 1.0 mm) (P < .05). Signal intensity did not differ significantly on T1-weighted, T2-weighted, and DW images between patients with and without hemorrhagic infarction. ADCs were significantly lower in patients with hemorrhagic infarction (1.20 ± 0.50 [× 10(-3) mm(2)/s]) than those without (2.04 ± 0.26 [× 10(-3) mm(2)/s]) (P < .01). With an ADC threshold of 1.80 [× 10(-3) mm(2)/s], sensitivity for hemorrhagic infarction was 0.88 (7 of 8), and specificity was 1.00 (6 of 6). CONCLUSION ADC measurements were useful for detecting hemorrhagic infarction in patients with ovarian torsion.

Abstract
Noninflammatory tubal abnormalities are rare in children and usually not well covered by traditional educational material. The presenting symptoms are nonspecific and are common to many other conditions, so its preoperative diagnosis is rarely made. The purpose of this study was to review the hospital charts and imaging findings in children and sexually inactive adolescents who showed fallopian tube pathology. Understanding of the pertinent findings of previous imaging examinations might assist radiologists in making the correct preoperative diagnosis and increase the likelihood of preserving the fallopian tubes. The clinical entities described in this article include isolated tubal torsion, paratubal cysts, hydrosalpinx, undescended/ectopic fallopian tube, and tubal inguinal hernia.

Abstract
We report a case of massive ovarian edema due to left adnexal torsion. On initial magnetic resonance (MR), unusual hemorrhages were demonstrated as several hypointense areas on T2-weighted images. The lack of contrast enhancement was also observed in the left adnexa. Abdominal pain resolved spontaneously, and then follow-up MR demonstrated the recovery of enhancement and hemorrhages as hyperintense signals on T1-weighted images.

Abstract
Clinical presentation of vascular disorders of female pelvis including placental adhesion, retained product of conception, ovarian venous thrombosis, varices, torsion and haemorrhagic infarct of ovary is often non-specific. Because of its availability, safety, and cost-effectiveness, ultrasound is the first investigation of choice. Computed tomography and MRI clearly depict the pelvic and retroperitoneal anatomy. This pictorial essay illustrates the complementary role of US, CT, and MRI in diagnosing vascular disorders of female pelvis.

Abstract
Adnexal torsion may occur in girls and adolescents. Often it is associated with ovarian diseases resulting in ovarian enlargement. Adnexal torsion may involve the ovary, fallopian tube or both, and the main symptom is acute pelvic pain. An 8-year-old girl complaining of acute pelvic and abdominal pain, who was previously diagnosed with precocious puberty and who received treatment with a GnRH analog, is reported. Ultrasound demonstrated a normal-sized uterus and bilaterally enlarged ovaries with multiple internal cysts. At laparotomy, we found a complete torsion in the right adnexa. The histological examination revealed massive edema associated with multiple antral follicles and reduction of the follicular reserve.

Abstract
OBJECTIVE To report the ultrasonographic aspects of ovarian torsion in nine pediatric cases. PATIENTS AND METHODS The age range was from 16 months to 14 years. The patients presented with a variety of symptoms, including pain in the site of torsion. Ultrasonography was performed in all patients, and color Doppler studies in four. RESULTS Ultrasonography showed a cystic mass in six patients, a solid mass with peripheral cysts in two patients and an adnexal cyst in one patient. Color Doppler revealed absence of flow in three patients. The patients were treated by coeliosurgery. CONCLUSION Ovarian torsion is a serious gynecologic emergency. Torsion is rare during childhood and has a non-specific clinical presentation. Ultrasound and Doppler are the imaging study of choice. The ovarian salvage was attributable to the combination of delay in patient presentation and surgical delay.

Abstract
PURPOSE To evaluate ultrasound (US) and magnetic resonance (MR) findings in the viable twisted adnexa. MATERIALS AND METHODS Ten patients underwent US and MR studies before surgical detorsion. Corrected cross-sectional area of the ovary was defined as cross-sectional area minus areas of cysts and follicles superior to 1 cm. On T2-weighted images, signal intensity of the stroma was graded as type 1 when it was equal to that of urine and type 2 when it was less than that of urine but markedly more than the contralateral side. RESULTS The tube was twisted in six cases and the ovary in nine cases. All adnexa were viable. The largest ovarian cross-sectional area and the largest corrected ovarian cross-sectional area of the twisted ovary were significantly larger than those of the contralateral ovary (P = 0.043 for US; P = 0.012 and 0.017, respectively, for MR). These ovaries contained types 1 and 2 hyperintensity in six cases and only type 2 hyperintensity in three cases. Tubal thickening was seen on MR in five cases. CONCLUSION Tubal thickening, enlargement of ovarian stroma as reflected by the corrected cross-sectional area, and hyperintensity of this stroma on T2-weighted images probably related to edema were useful findings in these viable torsions.

Abstract
We describe a case of severe spontaneous ovarian hyperstimulation syndrome (OHSS) with MR findings. MR scans showed bilateral symmetric enlargement of ovaries with multiple cystic changes, giving the classic "wheel-spoke" appearance. There was no definite abnormally thickened or enhanced wall, but there was internal hemorrhage in some chambers. To avoid unnecessary laparotomy, we emphasize the importance of careful diagnosis to differentiate spontaneous OHSS from ovarian cystic neoplasms.
