Abstract
PURPOSE The multifactorial nature of patellofemoral instability requires a comprehensive assessment of the affected patients. While an association between tibial tuberosity (TT) torsion and patellofemoral instability is known, its specific effect has not yet been investigated. This study investigated the effect of TT torsion on patellofemoral instability. METHODS This retrospective cohort study compared patients who underwent surgical intervention for patellofemoral instability and asymptomatic controls. TT torsion was measured in addition to other commonly assessed risk factors for patellofemoral instability using standardised computed tomography (CT) data of the lower extremities. The diagnostic performances of the assessed parameters were evaluated using receiver operating characteristic curve analysis and odds ratios (ORs) were calculated. RESULTS The patellofemoral instability group consisted of 79 knees, compared to 72 knees in the asymptomatic control group. Both groups differed significantly in all assessed parameters (p < 0.001), except for tibial torsion (n.s.). Among all parameters, TT torsion presented the best diagnostic performance for predicting patellar instability with an area under the curve of 0.95 (95% confidence interval [CI], 0.91-0.98; p < 0.001). A cut-off value of 17.7° yielded a 0.87 sensitivity and 0.89 specificity to predict patellar instability (OR, 55.2; 95% CI, 20.5-148.6; p < 0.001). CONCLUSION Among the evaluated risk factors, TT torsion had the highest predictive value for patellofemoral instability. Patients with TT torsions ≥ 17.7° showed a 55-fold increased probability of patellofemoral instability. Therefore, TT torsion should be included in the assessment of patients with patellofemoral instability. LEVEL OF EVIDENCE Level III.

Abstract
PURPOSE The purpose of this study was to find out whether the torsions of the femur and tibia are dependent on the coronal plane alignment of the knee (CPAK) type. METHODS Five hundred patients (1000 legs) were included, who received a whole leg standing three-dimensional (3D) radiograph using EOS imaging (EOS Imaging, Paris, France). SterEOS software was used for digital reconstruction. Femoral and tibial torsions were determined by analysing 3D reconstructions of each leg. Femoral torsion was defined as the angle between the femoral neck axis (FNA) and the posterior condylar axis (PCA). Tibial torsion was defined as the angle between the axis tangent to the posterior part of the tibia plateau and the transmalleolar axis. Arithmetic hip-knee-ankle angle (aHKA) and joint-line obliquity (JLO) were also determined, allowing each leg to be assigned one of nine possible phenotypes according to CPAK. RESULTS The mean femoral torsion in CPAK type 1 was significantly higher (+ 2.6° ± 0.8°) than in CPAK type 4 (p = 0.02). All other CPAK types did not differ in the degree of femoral torsions. No differences could be demonstrated for the tibial torsion. CONCLUSION There is a correlation between the coronal alignment of the lower limb and femoral torsion. This may provide the basis for extending the CPAK classification beyond the coronal plane. LEVEL OF EVIDENCE Level III.

Abstract
BACKGROUND Transabdominal ultrasound (US) is first-line imaging to evaluate ovaries in girls presenting to the emergency department (ED) with suspected ovarian torsion. Ovaries may be difficult to visualize sonographically; therefore, prompt diagnosis using US alone can be challenging. Rapid MRI as first-line imaging may help streamline patient throughput, especially with increasing MRI availability in the ED. OBJECTIVE To assess feasibility of rapid MRI for diagnosis of ovarian torsion. MATERIALS AND METHODS A retrospective, single-center IRB approved study of MRI performed in female pediatric patients presenting with abdominopelvic pain from August 2022 to January 2023. Imaging occurred according to one of three clinical pathways (US-first approach vs MRI-first approach vs US + MRI-second-line approach). A rapid three-sequence free-breathing MRI protocol was utilized. Frequency of ovarian torsion and secondary diagnoses was recorded. Length of MR scan time, time from ED arrival to time of diagnosis, and whether patient had US prior to MR exam were obtained. A historical cohort of patients with US only performed for assessment of ovarian torsion were evaluated for length of the US examination and time from ED arrival to time of diagnosis. Intervals were compared using the uncorrected Fisher's least significant difference and Turkey's multiple comparison tests. RESULTS A total of 140 MRI exams (mean age 14.6 years) and 248 historical US exams (mean age 13.5 years) were included. Of the patients with MRI, 41 (29%) patients were imaged with US + MRI and 99 (71%) imaged with MRI only; 4% (6/140) MR exams were suspicious for ovarian torsion, with one true positive case (1/6 TP) and 5 false positive cases (5/6 FP); 26.4% (37/140) of exams had secondary diagnoses. Median MRI scan time was 11.4 min (4.4) vs median historical US scan time was 24.1 min (19.7) (P<0.001). Median time from arrival in ED to MRI read was 242 (140). Median time from arrival in ED to US only read was 268 min (148). This was not a statistically significant difference when compared to the MRI only cohort. CONCLUSION First-line MRI imaging for evaluation of ovarian torsion is a rapid and feasible imaging modality for female patients in the emergent setting.

Abstract
A 2.5-year-old male-castrated rabbit presented with acute abdominal pain, lethargy, and anorexia. Digital radiography revealed increased left-sided hepatomegaly, gastric dilation, and decreased peritoneal serosal detail. Abdominal ultrasonography identified a torsed left liver lobe, gastric dilation, and peritoneal effusion. Surgery confirmed a left medial liver lobe torsion, with subsequent lobectomy and seven days of hospitalization. The patient re-presented 2 days after discharge and suddenly died while hospitalized, with acute gastric rupture, fulminant peritonitis, and multifocal hepatic infarcts diagnosed on necropsy. We believe this is the first recorded imaging diagnosis of a left medial liver lobe torsion in a rabbit.

Abstract
An 8-year-old, spayed, female poodle presented with exercise intolerance, lethargy, respiratory distress, retching, hyporexia and diarrhoea. Thoracic radiographs revealed increased opacity in the left cranial thoracic region. The fifth and sixth ribs appeared to be bulging cranially to caudally, and CT and surgical exploration confirmed the presence of a thoracic wall defect in that area. CT showed abrupt occlusion of the bronchus that branches into the left cranial lobe and consolidation of the caudal segment of left cranial lung lobe, which led to the diagnosis of lung lobe torsion. A thoracotomy was performed, the twisted lung lobe was surgically excised, and the defect in the thoracic wall was repaired. Respiratory distress gradually improved after the surgery, and there were no identified complications within the 2-year period following the procedure. Based on our literature search, this is the first reported case of lung lobe torsion caused by a thoracic wall defect in a dog.

Abstract
OBJECTIVE To analyze characteristics of acute and chronic ovarian torsion, review treatment recommendations, and present possible surgical techniques for fertility preservation in young women. DESIGN Literature review and demonstration of perioperative management of ovarian torsion using radiologic images and intraoperative video footage. Ovarian torsion is mostly mentioned in context of gynecologic emergencies, where acute ovarian torsion with arterial obstruction leads to ovarian ischemia and necrosis. However, ovarian torsion can also occur as a partial or intermittent torsion with venous and lymphatic obstruction, followed by ovarian swelling. In both cases, surgical management of ovarian torsion commonly includes oophorectomy, although leading guidelines recommend preservation of the ovary. We here aimed to raise awareness for the clinical features of ovarian torsion and demonstrate adequate perioperative management, thereby avoiding surgical overtreatment in young women. SETTING Medical University of Vienna, Department of Obstetrics and Gynecology. PATIENT(S) We present a case of acute ovarian torsion with a consequently ischemic ovary as well as a case of chronic ovarian torsion with related massive ovarian edema. The patients included in this video gave consent for publication of the video and posting of the video online, including social media, the journal website, scientific literature websites (such as PubMed, ScienceDirect, Scopus, etc.), and other applicable sites. INTERVENTION(S) Laparoscopic management with detorsion of the torquated ovaries, cystectomy on an ischemic ovary and oophoropexy to the pelvic side wall and utero-ovarian ligament to prevent recurrence. MAIN OUTCOME MEASURES Postoperative relief of pain and normalization of ovarian size and morphology on ultrasound imaging. RESULTS The current cases show successful conservative surgical management of ovarian torsion, hence preserving hormonal function and fertility in young women. CONCLUSION Although it is recommended to preserve fertility in young women affected by ovarian torsion, surgical overtreatment by means of oophorectomy is still common in clinical routine. Increasing awareness for the clinical characteristics of acute and chronic ovarian torsion, as well as for the importance of preservation of the ovary, is crucial. We therefore believe that ovarian torsion and its surgical management deserve increased attention in the future.

Abstract
PURPOSE The aim of this study was to compare MRI-based torsion measurements of the lower limb to a well-established CT-based assessment in a prospective inter- and intraindividual approach. METHODS A total of 26 patients (age 28.8 years ± 11.0) were enrolled beginning in January 2021 until August 2022. Inclusion criteria were the clinical indication for torsion measurement of the lower limb. CT and MRI imaging were performed with a standard operating procedure, to ensure that all patients were examined in a standardized position. The examinations were planned on a coronal scout view based on prominent anatomical landmarks. Femoral and tibial torsion were measured individually. Torsion measurements were analysed twice: immediately after examination and after 3 weeks. Subsequently, intra-rater and parallel test reliability was calculated accordingly. RESULTS High significant results for CT and MRI measurements for both tibia (MRI: r = 0.961; p ≤ 0.001; CT: r = 0.963; p ≤ 0.001) and femur (MRI: r = 0.980; p ≤ 0.001; CT: r = 0.979; p ≤ 0.001) were obtained by calculated intra-rater reliability, showing that measurements were highly consistent for MRI and CT, respectively. Parallel test reliability for time point 1 as well as time point 2 was also highly significant and ranged from r = 0.947 to r = 0.972 (all with p ≤ 0.001, respectively) for both tibia and femur, showing a high concordance between the two measurements. CONCLUSION Measurement of tibial as well as femoral torsion was comparable for CT and MRI measurement. Therefore, this study supports MRI measurement as an equivalent alternative for CT measurement concerning torsional malalignment to reduce exposure to radiation. LEVEL OF EVIDENCE Level II.

Abstract
Omental torsion is a very rare cause of acute abdomen. Clinically, it mimics other common pathologies such as acute appendicitis, acute diverticulitis and acute cholecystitis. It is therefore no surprise, that it was rarely diagnosed pre operatively before the advent and easy availability of modern imaging techniques. CT scan, in particular, can diagnose omental torsion with confidence pre operatively. This can make conservative treatment possible in cases of primary omental torsion and guide regarding the appropriate treatment in cases of secondary torsion. We present a case of a young male patient who presented to Emergency department with symptoms of acute abdomen. Clinical and laboratory findings were non-specific for any specific cause of acute abdomen. CT scan, however, showed omental fat stranding with whirlpool sign representing omental torsion which was seen to be secondary to left inguinal hernia. Patient was operated in emergency and necrotic omentum was resected and hernia repaired. Post-operative recovery was uneventful.

Abstract
Penile torsion is the abnormal three-dimensional twisting of penile corporal bodies. It can be classified as mild, moderate, or severe, depending on the degree of torsion. Severe penile torsion (>90°) is a very rare condition, with an estimated incidence of 0.4%-1% among all penile torsion cases. Our patient was a 37-year-old man complaining of a 2-year history of lower urinary tract symptoms. These symptoms appeared after the patient sustained an iatrogenic injury during Foley catheter insertion. Physical examination incidentally revealed an obvious counterclockwise penile rotation of 180°. Several theories have been proposed to explain the etiology of penile torsion, including theories based on genetic factors, abnormal urethral development, and abnormal attachment of the dartos fascia to the skin. Penile torsion may be associated with other penile anomalies, including chordee, hypospadias, and epispadias; however, it is often detected as an isolated finding. Clinical examination is sufficient to confirm its diagnosis without the need for further imaging. While no standardized procedure has been indicated for all penile torsion cases, the severity of torsion and the presence of other anomalies determine the most suitable procedure. No reports on the imaging features of penile torsion (irrespective of the degree of torsion) are available. We present the first such report on the imaging features, including advanced magnetic resonance imaging findings, of a 180° penile torsion in an adult patient.

Abstract
Isolated fallopian tube torsion is a rare cause of acute abdominal pain in adolescent females. It is known to be a surgical emergency as it may lead to ischemia of the fallopian tube which can result in necrosis, infertility or infection. Presenting symptoms and radiographic findings are vague making diagnosis difficult, often requiring direct visualization in the operating room to make the definitive diagnosis. There has been an increase in this diagnosis at our institution in the previous year prompting compilation of cases and a literature review.

Abstract
STUDY OBJECTIVE To create a decision support tool based on machine learning algorithms and natural language processing (NLP) technology, to augment clinicians' ability to predict cases of suspected adnexal torsion. DESIGN Retrospective cohort study SETTING: Gynecology department, university-affiliated teaching medical center, 2014-2022. PATIENTS This study assessed risk-factors for adnexal torsion among women managed surgically for suspected adnexal torsion based on clinical and sonographic data. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS The dataset included demographic, clinical, sonographic, and surgical information obtained from electronic medical records. NLP was used to extract insights from unstructured free text and unlock them for automated reasoning. The machine learning model was a CatBoost classifier that utilizes gradient boosting on decision trees. The study cohort included 433 women who met inclusion criteria and underwent laparoscopy. Among them, 320 (74%) had adnexal torsion diagnosed during laparoscopy, and 113 (26%) did not. The model developed improved prediction of adnexal torsion to 84%, with a recall of 95%. The model ranked several parameters as important for prediction. Age, difference in size between ovaries, and the size of each ovary were the most significant. The precision for the "no torsion" class was 77%, with a recall of 45%. CONCLUSIONS Using machine learning algorithms and NLP technology as a decision-support tool for the diagnosis of adnexal torsion is feasible. It improved true prediction of adnexal torsion to 84% and decreased cases of unnecessary laparoscopy.

Abstract
Torsional, angular, and linear measurements in a paediatric population are clinically important but not well defined and understood. Different methods of measurement and discrepancies between assessors leads to a lack of understanding of what should be defined as typical or atypical for the growing skeleton. From a large dataset of 333 paediatric CT scans, we extracted three-dimensional torsional, angular, and linear measurements from the pelvis, femur, and tibia/fibula. Sex differences in linear measurements were observed in bones of children aged 13+ (around puberty), but femoral and tibial torsion were similar between males and females. The rotational profile (femoral anteversion minus tibial torsion) tended to increase with growth. Epicondylar, condylar, and malleolar widths were smaller in females than males for the same bone length after the age of 13 years, which could explain why females may be more at risk for sport injuries during adolescence. This rich dataset can be used as an atlas for researchers and clinicians to understand typical development of critical rotational profiles and linear bone measurements in children.

Abstract
OBJECTIVE To evaluate the diagnostic accuracy of different ultrasound signs for diagnosing adnexal torsion, using surgery as the reference standard. METHODS This was a systematic review and meta-analysis of studies published between January 1990 and November 2021 evaluating ovarian edema, adnexal mass, ovarian Doppler flow findings, the whirlpool sign and pelvic fluid as ultrasound signs (index tests) for detecting adnexal torsion, using surgical findings as the reference standard. The search for studies was performed in PubMed/MEDLINE, CINAHL, Scopus, The Cochrane Library, ClinicalTrials.gov and Web of Science databases. The Quality Assessment of Diagnostic Accuracy Studies-2 (QUADAS-2) tool was used to evaluate the quality of the studies. Pooled sensitivity, specificity, and positive and negative likelihood ratios were calculated separately, and the post-test probability of adnexal torsion following a positive or negative test was also determined. RESULTS The search identified 1267 citations after excluding duplicates. Eighteen studies were ultimately included in the qualitative and quantitative syntheses. Eight studies (809 patients) analyzed the presence of ovarian edema, eight studies (1044 patients) analyzed the presence of an adnexal mass, 14 studies (1742 patients) analyzed ovarian Doppler flow, six studies (545 patients) analyzed the whirlpool sign and seven studies (981 patients) analyzed the presence of pelvic fluid as ultrasound signs of adnexal torsion. Overall, the quality of most studies was considered to be moderate or good. However, there was a high risk of bias in the patient-selection and index-text domains (with the exception of the whirlpool sign) in a significant proportion of studies. Pooled sensitivity, specificity, and positive and negative likelihood ratios of each ultrasound sign were 58%, 86%, 4.0 and 0.49 for ovarian edema, 69%, 46%, 1.3 and 0.67 for adnexal mass, 65%, 91%, 7.6 and 0.38 for the whirlpool sign, 53%, 95%, 11.0 and 0.49 for ovarian Doppler findings and 55%, 69%, 1.7 and 0.66 for pelvic fluid. Heterogeneity was high for all analyses. CONCLUSIONS The presence of an adnexal mass or pelvic fluid have poor diagnostic accuracy as ultrasound signs of adnexal torsion, while the presence of ovarian edema, the whirlpool sign and decreased or absent ovarian Doppler flow have good specificity but moderate sensitivity for detecting adnexal torsion. © 2022 The Authors.

Abstract
PURPOSE The aim of this study was to investigate the association of clinical, laboratory, and ultrasound findings with the surgical diagnosis of adnexal torsion in a retrospective cohort of women operated for suspected torsion during pregnancy. MATERIALS AND METHODS A multicenter retrospective study of pregnant women who underwent urgent laparoscopy for suspected adnexal torsion during 2004-2019 in three tertiary medical centers. RESULTS Adnexal torsion was found in 143/208 (68.8 %) cases. Women with adnexal torsion had lower parity and lower rates of previous cesarean section, but higher rates of fertility treatments and multiple gestations, and were more likely to report right lower abdominal pain, with shorter duration of symptoms (< 24 hrs) and vomiting but not nausea. Women with adnexal torsion were found to have higher rates of sonographic findings suggestive of ovarian edema, while normal-appearing ovaries on ultrasound were more common in women without torsion. A multivariate logistic regression analysis showed that complaints of right abdominal pain were positively associated with adnexal torsion (aOR [95 % CI] 5.03 (1.45-17.49), while previous cesarean delivery and ultrasound findings of normal-appearing ovaries were negatively associated with adnexal torsion (aOR of 0.17 (0.05-0.52) and 0.10 (0.02-0.43), respectively). CONCLUSION Clinical characteristics and ultrasound findings may be incorporated into the emergency room workup of pregnant women with suspected adnexal torsion.

Abstract
PURPOSE To determine the clinical and ultrasound features of dermoid-associated adnexal torsion. METHODS Forty-four patients with at least one dermoid and ultrasound ≤ 30 days of surgery were retrospectively reviewed by three radiologists. Ultrasound and clinical findings were compared to intra-operative findings using Fisher's exact test or Mann-Whitney test with p < 0.05 to determine statistical significance.Please check and confirm that the authors and their respective affiliations have been correctly identified and amend if necessary.Correct. No edit RESULTS: Twenty patients had torsion, while 24 patients did not. Patients with dermoid-associated torsion were more likely to present to emergency department (ED) (100% vs 13%; p < 0.001) and have acute unilateral pelvic pain (100% vs 42%; p < 0.001). On ultrasound, patients with torsion had larger dermoids (median largest dimension 9.0 cm (IQR 7.7-11.1) vs 6.0 cm (IQR 4.4-7.5); p < 0.001), displaced dermoid anterior or superior to the uterus (59% vs 21%; p = 0.016), and ipsilateral adnexal fluid (41% vs 4%; p = 0.003). Displaced dermoid and ipsilateral adnexal fluid had substantial (kappa = 0.72) and moderate inter-rater agreement (kappa = 0.49), respectively. The combination of ED presentation and each statistically significant ultrasound feature (dermoid size ≥ 5.0 cm, displaced dermoid, and ipsilateral adnexal fluid) yielded high specificity and positive predictive value (ranging from 93-100% to 92-100%, respectively). The combination of ED presentation and dermoid size ≥ 5.0 cm yielded the highest sensitivity, negative predicative value, and accuracy (100%, 100%, and 96%, respectively).Please check and confirm whether the edit made to the article title is in order.Looks great. No edits. Thank you! CONCLUSION Although the diagnosis of adnexal torsion in the presence of an ovarian dermoid is traditionally challenging, the combination of ED presentation and ultrasound features increase diagnostic confidence of dermoid-associated adnexal torsion.

Abstract
We herein report a rare case of torsion of a wandering spleen in a patient with myeloproliferative disease. A 66-year-old Japanese woman presented to our hospital with abdominal pain and a fever. She had a medical history of polycythemia and secondary myelofibrosis. Abdominal enhanced computed tomography showed an enlarged spleen without enhancement in the lower pelvic region. The clinical diagnosis was severe torsion of a wandering spleen in a patient with myeloproliferative disease, necessitating surgical intervention. Splenectomy was performed after de-rotating to revascularize the spleen. After the operation, the platelet count gradually increased, and aspirin was administered to prevent thrombosis.

Abstract
OBJECTIVES Ovarian torsion (OT) is an emergency that mandates early detection and surgical detorsion to avoid catastrophic consequences of further adnexal injury. Prompt ultrasound is critical for accurate diagnosis. Traditionally, evaluation of arterial and venous flow was used as a diagnostic tool for OT, but recent radiologic research has indicated that ovarian size and size discrepancy between sides is a better diagnostic criterion. This study seeks to determine whether ovarian size discrepancy or vascular flow to the ovary is more accurate in the diagnosis of OT in the pediatric emergency population and to better describe symptoms that distinguish OT from other abdominal and pelvic pathology. METHODS This was a retrospective, cross-sectional study evaluating all female pediatric patients, aged 1 to 18 years, who underwent a pelvic ultrasound to evaluate for OT over a 2-year period in our pediatric emergency department. Patients suitable for inclusion were identified via Nuance mPowerTM, a search engine that provides clinical analytics based on radiology reports generated within our institution. RESULTS We reviewed the medical records of 193 female patients aged 1 to 18 years, all of whom had a pelvic ultrasound (with or without Doppler) to evaluate for OT during the study period. In comparing ovarian size on ultrasound, patients with OT had a significantly larger magnitude of difference in ovarian volume than patients without torsion (5.57× [interquartile range, 3-12.5] vs 1.56× [interquartile range, 1.24-2.25; P < 0.001]). Ovarian torsion was associated with a 33-fold increased risk of lack of arterial flow (relative risk, 33.33) and with a 9-fold increased risk of lack of venous flow (relative risk, 9.27), when compared with those patients without OT. Patients with OT were significantly more likely to have emesis and peritoneal signs on examination, as well as previous history of OT (P = 0.01, 0.02, and 0.002, respectively) than those without OT. All patients with OT reported abdominal pain. CONCLUSIONS We found that a large size discrepancy between ovaries is indicative of OT. Our data also suggest that presence of Doppler flow on ultrasound cannot be used to exclude OT but that lack of Doppler flow on ultrasound is a significant diagnostic marker. As previous studies have also found, clinical symptoms of OT are nonspecific and do not offer any certainty in differentiating OT from other pathologies.

Abstract
Pediatric patients of various ages, from infancy through adolescence, can have ovarian torsion. Torsion may not only be confined to the ovaries but may also involve the isolated cyst, tube, and even the uterus. In this pictorial review, we review the spectrum of torsion in pediatric (from infants to adolescents) female pelvis, emphasizing imaging methods.

Abstract
PURPOSE To establish the utility of an ultrasonographic scoring system for the diagnosis of adnexal torsion. METHODS We retrospectively analyzing 358 adnexal torsion cases. Using Pearson's χ2 test we determined whether ultrasonographic signs were significantly associated with adnexal torsion. Receiver operating characteristic curves were used to evaluate the diagnostic efficacy of the system. Ultimately by using binary logistic regression we established a precise and convenient scoring system. RESULTS The torsion score was based on five criteria that were identified to be independently associated with adnexal torsion: (1) abnormal position of the index adnexa (odds ratio [OR], 2.311); (2) presence of a mass or cyst (OR, 3.495); (3) unilateral ovarian enlargement (OR, 3.051); (4) vascular pedicle twisting (OR, 2.105); and (5) peripheral hypervascularity of the corpus luteum with ovarian edema(encapsulating cyst sign) (OR, 4.164).patients with torsion who scored 0, have a predicted diagnosis rate of 20.9%; patients whose scores were 1,2 have a predicted probability of 41.8% and 66.15%, respectively. For patients with torsion scores of 3, 4, and 5, predicted diagnosis rates were 84.16%, 93.52%, and 98.27%, respectively. CONCLUSION The ultrasonographic scoring system is feasible and precisely diagnoses adnexal torsion using ultrasound.

Abstract
OBJECTIVE To compare features of pre-menarchal and post-menarchal patients with adnexal torsion. METHODS We reviewed hospital records to note examination findings, laboratory work-up, imaging results, operative findings and course during hospital stay for 56 girls aged from 7 days to 17 years with adnexal torsion presenting between January, 2012 and December, 2020. RESULTS 31 girls were pre-menarchal. Pain was the most common symptom. There were significant differences in the volume of the ovary visualized in ultrasound in amenorrheic and menstruating girls [median (IQR) 78234 (39600, 183600) mm3 vs 243432 (158661, 388800) mm3; P=0.004]. Pain was the most common symptom. Over the years, there was an increase in laparoscopic procedures, and efforts to preserve the ovary after the torsion. CONCLUSIONS The differential diagnosis in the case of abdominal pain should include adnexal torsion both in non-menstruating and menstruating girls.

Abstract
OBJECTIVE Primary omental torsion (POT) is a rare condition in children often misdiagnosed because of a lack of clinical manifestations. Here we present insights gained from the treatment of pediatric POT cases at a single center over 8 years and summarize some influencing factors found in diagnosis and treatment, in order to reduce the misdiagnosis of POT in children in the future. METHODS Demographic and clinical data of 17 children with POT treated in Shanghai Children's Hospital, Shanghai Jiaotong University from June 2012 to December 2020 were reviewed. RESULTS The mean age of the 17 pediatric patients was 7.65 ± 2.12 years (range: 4-12 years), sixteen were male. The average time from the pain onset to operation was 73.82 ± 47.21 h (range: 21-144 h). In 5 cases, the ultrasound scan revealed a low-intensity inflammatory mass in the abdominal cavity. Only 1 of the 17 patients had normal body mass index, while others were overweight or obese. The mean computed tomography (CT) value of the mass in the lower right abdomen was - 58.74 ± 10.32 HU (range: - 70 to - 46 HU), which is close to that of its own abdominal wall fat [- 46.29 ± 9.45 HU (range: - 62 to - 32 HU)]. The location of the mass was located in front of the right colon in ten cases, except for two cases near the ligamentum teres. Five patients had whirl sign on CT images and 8 patients had pelvic fluid. Five cases were diagnosed as acute appendicitis and 12 were diagnosed as POT, the preoperative diagnosis was correct in 70.59% of cases. All 17 patients were treated with laparoscopic omentectomy. The average duration of hospitalization was 5.53 ± 1.12 days (range: 4-8 days). All cases were followed up. 1 case relapsed 8 months post operation, while the remaining cases had no complications. CONCLUSION POT is rare in children with acute abdominal pain, which is more common in obese boys. The fatty mass in front of colon and between rectus abdominis sheath in CT image is specific, which is helpful for diagnosis of POT. Laparoscopy is an effective method for the treatment of POT in children.

Abstract
OBJECTIVES The aim of the study was to evaluate the clinical and sonographic parameters associated with a correct or incorrect diagnosis of adnexal torsion made by resident/attending physicians who are not expert sonographers. METHODS A retrospective study design included women who presented to the Emergency Department (ED) of a tertiary medical center between 2010 and 2019 with acute lower abdominal pain, who were subsequently diagnosed laparoscopically with adnexal torsion. Women who were correctly diagnosed in the ED by an obstetrician-gynecologist who was not an expert sonographer were compared for clinical and sonographic parameters with women who were initially incorrectly diagnosed and underwent a second ultrasound examination by an expert sonographer following admission. RESULTS Of 118 women with surgically proven adnexal torsion, 76 were correctly diagnosed in the ED and 42 were initially incorrectly diagnosed. The correctly diagnosed group was characterized by a significantly shorter mean time from admission to surgery, higher rate of vomiting, shorter duration of abdominal pain, and higher rate of prior torsion (P < .05). Physicians who made the correct diagnosis utilized more sonographic parameters than those who did not, namely ovarian size, ovarian edema, and Doppler flow. The correctly diagnosed group had a higher rate of bluish-black (ischemic) adnexa at laparoscopy, but a higher rate of recovery following detorsion. CONCLUSIONS Physicians in the ED should be alerted to the need to address some basic sonographic features when adnexal torsion is suspected. The diagnostic accuracy of adnexal torsion can be improved by utilizing simple sonographic markers, even in the ED setting.

Abstract
OBJECTIVES We performed a meta-analysis of studies examining the computed tomography (CT) features of adnexal torsion (AT). METHODS We searched PubMed, Embase, Web of Science, and the Cochrane Library for studies involving the proportion of CT features in patients with AT and that used surgery as the reference test. Study quality was assessed using the Newcastle-Ottawa scale and the Agency for Healthcare Research and Quality tool. RESULTS Twelve articles involving 483 patients were included. The pooled proportion of right-sided adnexal lesion was 54% (95% confidence interval [CI]: 49%-56%). The pooled proportions of the ovarian lesion histopathological types were: benign germ cell tumors, 33% (95% CI: 28%-37%); benign cystic lesions, 26% (95% CI: 21%-30%); benign epithelial neoplasms, 24% (95% CI: 20%-29%); sex cord-stromal tumors, 4% (95% CI: 2%-6%); borderline neoplasms, 3% (95% CI: 1%-6%); and hemorrhagic cysts, 2% (95% CI: 0%-3%). The pooled proportions of CT features were: Adnexal enlargement, 99% (95% CI: 98%-99%); adnexal with mass, 98% (95% CI: 97%-100%); twisted pedicle, 81% (95% CI: 78%-83%); mass with thickened wall, 77% (95% CI: 73%-81%); tubal thickening, 73% (95% CI: 68%-77%); abnormal location of adnexa, 69% (95% CI: 63%-75%), pelvic ascites, 43% (95% CI: 38%-49%); pelvic fat infiltration, 41% (95% CI: 34%-48%); uterine deviation, 37% (95% CI: 31%-42%); and lack of enhancement, 20% (95% CI: 14%-25%). CONCLUSION Adnexal enlargement, adnexal mass, and twisted pedicle may be the most important CT features for diagnosing AT.

Abstract
A 4-year-old, neutered male, mixed breed Old English sheepdog was presented for evaluation and treatment of anorexia, vomiting, and diarrhea. Presumptive severe pancreatitis was diagnosed based on the referral bloodwork. Abdominal ultrasonography identified a suspected liver lobe torsion based on the presence of a normal spleen. However, an exploratory laparotomy identified a splenic torsion in addition to a grossly normal spleen. Key clinical message: This case demonstrates that a second, potentially large area of splenic tissue (ectopic or accessory) can be present in the dog; therefore, the presence of a normal appearing spleen on abdominal ultrasonography does not rule out splenic torsion.

Abstract
Omental torsion is a rare cause of abdominal emergency. Due to its clinical presentation and according to its localisation it is seldom diagnosed preoperatively as it imitates other more common diagnoses leading to surgical revision quite precisely. In this case report the authors present omental torsion with partial omental necrotisation in the right upper quadrant, imitating acute cholecystitis. The condition was managed by laparoscopic resection with a good clinical course postoperatively.

Abstract
BACKGROUND Pulmonary torsion is a rare complication following thoracic surgery. CASE PRESENTATION A man in his seventies was diagnosed with stage IIIA lung cancer occupying the right upper lobe, and lobectomy was performed through posterolateral thoracotomy. Postoperative chest X-rays revealed extensive, progressive middle lobe opacities on postoperative day 0 and 1, with no corresponding clinical or bronchoscopic findings. Contrast-enhanced computed tomography raised suspicion of middle lobe torsion, and exploratory surgery confirmed the finding of a necrotic middle lobe with 180 degrees of torsion. The middle lobe was resected and the patient recovered well. INTERPRETATION Pulmonary lobar torsion is a rare but potentially life-threatening complication following thoracic surgery that should not be overlooked even in the absence of symptoms that raise concern. Bronchoscopy and radiological imaging may suggest the condition, but the final diagnosis is made surgically.

Abstract
Primary torsion of large omentum is a rare cause of abdominal pain. The knowledge of this disease is essential for surgeons. It plays an important role in differential diagnosis of acute abdomen. The authors present two cases of primary omental torsion. They describe the diagnostic and therapeutic process. Diagnosis of omental torsion is difficult. Frequently, it presents with abdominal pain and imitates other acute abdominal diseases such as acute appendicitis in most cases. It is difficult to diagnose before surgical revision is approached. Laboratory and paraclinical examinations may not provide any clear findings. Laparoscopic revision is the method of choice, with confirmation of the diagnosis and laparoscopic resection of the ischemic part of omentum.

Abstract
In this review, we investigated the diagnostic value of the sonographic "whirlpool sign" in identifying ovarian torsion. This was done by performing a search in PubMed, Scopus, Embase, Web of Science, CINAHL, and Google scholar. Additional search for the grey literature was made in EThOS.bl.uk, explore.bl.uk, opengrey.eu, greylit.org, and clinicaltrials.org. A total of eight studies were included in this meta-analysis. Sensitivity and specificity of whirlpool sign were extracted from the studies and computed into the Metadisc statistical software for pooled analysis. The whirlpool sign showed a high sensitivity and specificity for the diagnosis of ovarian torsion.

Abstract
This report describes a rare case of isolated fallopian tube torsion (IFTT) in a premenarchal 11-year-old girl. The patient presented with subacute abdominal pain, associated with nausea and vomiting. Sonographic findings revealed left tube enlargement with free intraperitoneal fluid. Doppler mapping was not unequivocal. During exploratory laparoscopy, a large pelvic necrotic mass was found to be a twisted left fallopian tube. After detorsion, salpingectomy was performed and the patient recovered promptly, showing no complications 3 months post operation. IFTT should be considered as a differential diagnosis of lower abdominal pain in adolescent girls with normal-appearing ovaries on ultrasound. Conservative management for fertility preservation is the ideal approach. Therefore, avoiding delay in laparoscopy is crucial.

Abstract
This is a case report of an adult female with omental infarction caused by internal herniation and omental torsion. The patient, who had no previous surgical record, presented with three days of pain in the right upper quadrant. Ultrasound evaluation showed no signs of cholecystitis, after which an abdominal computed tomography confirmed the diagnosis. The patient underwent laparoscopic omentectomy, with an uneventful recovery. This case highlights the importance of radiological and surgical awareness of this rare condition.

Abstract
OBJECTIVES To determine predictive values of isolated and combined ultrasound signs in the diagnosis of adnexal torsion. METHODS This work was a retrospective study of 129 adult female patients who underwent an ultrasound examination followed by a definitive surgical procedure within a 24-hour period to determine whether adnexal torsion was present. RESULTS The positive predictive value (PPV) of the ultrasound diagnosis of adnexal torsion was 82.2%. The statistically significant ultrasound signs in multivariate logistic regression with single-predictor analyses were relative enlargement of the ovary, an abnormal adnexal position, a twisted vascular pedicle, and the follicular edema "ring sign." Possible combinations of these ultrasound criteria showed high specificities (74%-100%), high PPVs (93%-100%), and lower sensitivities (29%-71%) and negative predictive values (24%-35%). Any combination that included a twisted vascular pedicle or the follicular ring sign as one of the signs had high odds ratios and positive likelihood ratios. CONCLUSIONS Ultrasound has a high PPV as a first-choice imaging modality in the diagnosis of adnexal torsion. The combinations of the following 4 statistically significant ultrasound signs, consisting of an abnormal position, relative enlargement of the index ovary, a twisted vascular pedicle, and the follicular edema ring sign, substantially narrow the imaging differential diagnosis in such cases. The presence of vascular pedicle twisting and the follicular ring sign was highly associated with a positive ovarian torsion diagnosis, with 100% specificity.

Abstract
Gastroschisis is an uncommon congenital defect of the abdominal wall resulting in intestinal prolapse, most commonly associated with short gut syndrome or bowel obstruction. Wandering spleen, movement of the spleen due to the underdevelopment of splenic ligaments, has a prevalence of 0.25% and is asymptomatic in 15% of paediatric cases. An 11-year-old patient, admitted with a history of gastroschisis repaired at birth, presents with 18 months of intermittent, worsening abdominal pain. Imaging demonstrated splenomegaly and tortuosity of the splenic vein with abnormal positioning of the superior mesenteric artery and vein. The patient was found to have a wandering spleen with subacute splenic infarct secondary to splenic torsion, necessitating emergent surgical intervention. This patient experienced an extremely rare complication of gastroschisis that has not previously been reported. This complication is caused by a lack of appropriate abdominal fixation points for the spleen.

Abstract
The diagnosis of ovarian torsion is challenging and relies mostly on morphologic findings. Occasionally, women or children with acute pelvic pain who have undergone an initial ultrasound (US) evaluation with results interpreted as negative for ovarian torsion will return with recurrent or increasing pain, prompting an US reevaluation. The flipped ovary sign refers to a demonstrable change in the orientation of the ovary on follow-up US examinations, recognized by changing positions of ovarian landmarks established by follicles, cysts, or masses. This sign is valuable for identifying ovarian torsion in these patients, even in the absence of classic morphologic or Doppler features of ovarian torsion.

Abstract
The incidence of postoperative pulmonary torsion is not frequent but it has a high mortality rate once it occurs, and prompt diagnosis and treatment are required. From past reports, it is considered effective to point out disruption of pulmonary blood flow by contrast-enhanced computed tomography (CT) examination for diagnosis. However, the comparison of pre- and post-operative plain CT images is considered to be useful in diagnosing lung torsion, and postoperative CT lung window setting sagittal images were examined in three cases of postoperative lung torsion. Results indicate that pulmonary torsion of the middle lobe after right lower lobectomy and the middle lobe after right upper lobectomy can be diagnosed by the present method.

Abstract
A 68-year-old man visited a physician with a chief complaint of difficulty breathing. Right pleural effusion was noted, and he was referred to our department for a close examination and treatment. Thoracoscopy was performed under local anesthesia, and pleural dissemination of lung adenocarcinoma was noted, so a chest drain was placed. Since poor right lung inflation persisted and whole right lung torsion was observed on computed tomography, thoracoscopy-assisted thoracotomic reduction of lung torsion was performed. In this patient, the right middle lobe and anterior chest wall were adhered, suggesting that whole right lung torsion occurred when atelectasis was formed due to pleural effusion.

Abstract
PURPOSE To look for the presence of "perifollicular rim sign" on non-contrast CT in surgically proven cases of ovarian or adnexal torsion. METHODS A retrospective analysis of abdominopelvic non-contrast CT examinations in surgically proven cases of ovarian or adnexal torsion was conducted seeking the presence of "perifollicular rim sign" in torsed ovaries. "Perifollicular rim sign" was defined as a complete ring of perifollicular hyperdensity around ovarian follicles with an attenuation value of > 50 HU and thickness > 1-2 mm. A positive sign was equated to the presence of perifollicular hemorrhage. Pre-operative non-contrast CT was available in 7 out of the 39 ovarian or adnexal torsions included in our study. RESULTS "Perifollicular rim sign" was present in 5 out of the 7 ovarian torsions on pre-operative non-contrast CT. MRI correlation was available in one patient. Ovarian enlargement (>4 cm) was present in all 7 cases. CONCLUSION In an appropriate clinical setting, presence of "perifollicular rim sign" in an enlarged ovary on non-contrast CT examination can be considered a useful additional sign for ovarian torsion.

Abstract
Liver lobe torsion (LLT) is an uncommon condition of unknown origin in dogs. Several reports describe the clinical features and outcome, but only few of them include the imaging characteristics of this disease. The aim of this descriptive case series was to describe the ultrasonographic (US) and multidetector-row computed tomographic (MDCT) features of LLT in a group of dogs. Five dogs were included in this single-center descriptive study, having both US, CT and surgical and histological confirmation of LLT available for review. Different US appearances have been found, both hypoechoic and hyperechoic liver lobes and heterogeneous mass-like lesions, with fluid and gas content. At three-phase MDCT examination, LLT appeared as fluid- and gas-filled lesions (consistent with abscess transformation), or as hypoattenuating hypovascular lobes. Two different vascular signs were also described: whirl sign or vascular interruption were seen in all cases, allowing a correct pre-surgical diagnosis in all the cases presented. Multiphase MDCT was a helpful imaging method for the correct pre-surgical diagnosis of LLT in dogs, and its use in the suspected cases is therefore advisable.

Abstract
Wandering spleen is a cause of acute surgical abdomen with serious consequences. It arises from an absence or weakness of the supporting suspensory splenic ligaments. There is often a delayed diagnosis due to its non-specific clinical presentation. This leads to stalled acquisition of confirmatory diagnostic imaging with resultant increased morbidity and mortality. Congenital or acquired absence of the left kidney results in loss of the splenorenal ligament, a key ligament to maintain normal splenic position in the abdomen. Two patients, one with OHVIRA (obstructed hemivagina ipsilateral renal anomaly) syndrome and another who underwent a left nephrectomy during infancy, developed a wandering spleen with acute splenic torsion in the setting of an absent left kidney. This case series aims to increase awareness to the likely predisposition for individuals with an absent left kidney to develop a wandering spleen.

Abstract
PURPOSE To investigate the accuracy of ultrasound in the diagnosis of adnexal torsion. MATERIALS AND METHODS Retrospective cohort analysis of 322 women, presenting to a tertiary medical center with acute abdominal pain, who underwent gynecological examination, sonographic evaluation and laparoscopic surgery, between 2010 and 2016. Findings for adnexal torsion were compared among three groups: positive sonographic findings consistent with surgically confirmed adnexal torsion (true positive, n = 228); negative sonographic findings inconsistent with surgically confirmed adnexal torsion (false negative, n = 42); and positive sonographic findings inconsistent with a surgical diagnosis other than adnexal torsion (false positive, n = 52). Outcome measures were sensitivity and positive predictive value of ultrasound, and its specific features, for the diagnosis of adnexal torsion. RESULTS The sensitivity of ultrasound for adnexal torsion diagnosis was 84.4 %, and the positive predictive value was 81.4 %. Edematous ovary and/or tube, as well as positive whirlpool sign had the highest sensitivity and positive predictive value. The false-negative group had the highest frequency of ovarian cysts (p = 0.0086) and the lowest frequency of ovarian edema (p < 0.0001). The false-positive group had the lowest proportion of pregnant women (p = 0.0022). Significantly more women in the true-positive group had a prior event of adnexal torsion (p = 0.026). CONCLUSION Ultrasound examination is highly accurate in the diagnosis of adnexal torsion. Clinicians should be aware of the presence of demographic and clinical characteristics that may positively or negatively affect sonographic diagnostic accuracy.

Abstract
BACKGROUND Accessory liver lobes and other congenital liver abnormalities are rare and most often asymptomatic. However, these abnormalities can result in liver torsion, requiring surgical resection. CASE REPORT We report a case of a 72-year-old woman with hepatic lobe torsion. She presented with an acute onset of chest pain and was discovered to have hypoperfusion of the left lobe of the liver on contrast-enhanced abdominal computed tomography (CT) scan. An exploratory laparotomy revealed left hepatic lobe torsion with irreversible ischemic changes requiring left hepatic lobe resection. CONCLUSION Even though hepatic torsion is rare, it should be considered in the differential diagnosis for abdominal pain and appropriately imaged so that surgical teams can prepare for the complex surgical procedure.

Abstract
A 61-year-old male patient presented to our hospital's emergency department with a history of worsening abdominal pain. The symptoms began as epigastric pain and later localized to the right lower quadrant. On physical examination, there was rebound tenderness mainly in the right lower quadrant and in the right upper quadrant. The laboratory results showed leukocytosis. Abdominopelvic computed tomography scan revealed that a definite twisting on the long axis with three complete counter-clockwise turns was observed in the vascular structures of greater omentum. At operation, the greater omentum was found to be twisted and gangrenous. The infarcted omentum was ligated at the pedicle and excised. Primary torsion of the omentum is one of the uncommon causes of acute abdominal pain. Although rarely diagnosed, the entity is important to the surgeon because it mimics the common causes of the acute surgical abdomen. Omental torsion usually occurs on the right side. Abdominal pain starts suddenly after a heavy meal or hard exercise, and is not accompanied with nausea, vomiting and anorexia. Abdominal computed tomography may show peculiar features suggestive of omental torsion. Treatment consists of ligation and resection of the involved portion of the omentum and recovery is usually rapid, uneventful and complete. Primary omental torsion should be considered in the differential diagnosis of acute abdomen. The surgeon must remain aware of the disease and search for it if, at laparotomy, other adequate cause is not found to explain the symptoms, especially if free sero-sanguineous fluid is found in the peritoneal cavity. KEY WORDS: Acute abdomen, Greater omentum, Omental torsion, Omental infarction, Omental necrosis.

Abstract
RATIONALE Wandering spleen (WS) is a rare clinical entity characterized by splenic hypermobility caused by absent or abnormal laxity of the suspensory ligaments, which fix the spleen in its normal position. Due to abnormal attachment, the spleen is predisposed to torsion and a series of complications. Pediatric WS is mostly reported in children aged <10 years, especially among infants aged <1 year; it is uncommon among toddlers between 1 and 3 years. To the authors' knowledge, only seven cases of WS have been described previously. Herein, we present the case of a 3-year-old toddler with WS and splenic torsion. PATIENT CONCERNS A 3-year-old boy was presented to the pediatric emergency room with a 2-day history of abdominal pain and vomiting. The ultrasonographic examination revealed a mass in the left upper abdomen cavity and absence of spleen in its normal position. Computed tomography showed an enlarged displaced spleen occupying the left abdomen cavity with an elongated splenic vascular pedicle (whirl sign), suggesting splenic torsion. DIAGNOSES The patient was diagnosed that had WS and splenomegaly, with or without complications due to splenic torsion. INTERVENTIONS The patient underwent emergency laparotomy and splenectomy due to nonviability after detorsion. OUTCOMES The postoperative course was uneventful, and the patient was discharged on the 7th day postoperatively without complications. The patient had favorable outcome over a 1-year follow-up. LESSONS Herein, we reported the case of a toddler with WS with splenic torsion. Moreover, after reviewing relevant studies in literature, we presented our findings on the diagnosis and treatment of toddlers with WS. Toddlers with WS are characterized by acute abdominal pain, unclear history description, examination restrictions, and high rates of life-threatening complications. High level of suspicion, careful physical examination, detailed history collection, and objective investigation are crucial in the management of toddlers with WS.
