Review
Abdominal pain is a common reason for emergency department visits, with many patients not receiving a definitive diagnosis for their symptoms. Non-gastrointestinal causes need to be considered in the workup of abdominal pain. A high index of suspicion is needed in order to develop a broad differential, and a thorough history and physical examination is paramount. This article will discuss some of these diagnoses, including can't miss diagnoses, common non-abdominal causes, and rare etiologies of abdominal pain.

Ultrasound in Obstetrics & Gynecology :... Dec 2020To describe the clinical and ultrasound characteristics of adnexal torsion.
OBJECTIVES
To describe the clinical and ultrasound characteristics of adnexal torsion.
METHODS
This was a retrospective study. From the operative records of the eight participating gynecological ultrasound centers, we identified patients with a surgically confirmed diagnosis of adnexal torsion, defined as surgical evidence of ovarian pedicle, paraovarian cyst and/or Fallopian tube twisted on its own axis, who had undergone preoperative ultrasound examination by an experienced examiner, between 2008 and 2018. Only cases with at least two available ultrasound images and/or videoclips (one grayscale and one with Doppler evaluation) were included. Clinical, ultrasound, surgical and histological information was retrieved from each patient's medical record and entered into an Excel file by the principal investigator at each center. In addition, two authors reviewed all available ultrasound images and videoclips of the twisted adnexa, with regard to the presence of four predefined ultrasound features reported to be characteristic of adnexal torsion: (1) ovarian stromal edema with or without peripherally displaced antral follicles, (2) the follicular ring sign, (3) the whirlpool sign and (4) absence of vascularization in the twisted organ.
RESULTS
A total of 315 cases of adnexal torsion were identified. The median age of the patients was 30 (range, 1-88) years. Most patients were premenopausal (284/314; 90.4%) and presented with acute or subacute pelvic pain (305/315; 96.8%). The surgical approach was laparoscopic in 239/312 (76.6%) patients and conservative surgery (untwisting with or without excision of a lesion) was performed in 149/315 (47.3%) cases. According to the original ultrasound reports, the median largest diameter of the twisted organ was 83 (range, 30-349) mm. Free fluid in the pouch of Douglas was detected in 196/275 (71.3%) patients. Ovarian stromal edema with or without peripherally displaced antral follicles was reported in the original ultrasound report in 167/241 (69.3%) patients, the whirlpool sign in 178/226 (78.8%) patients, absent color Doppler signals in the twisted organ in 119/269 (44.2%) patients and the follicular ring sign in 51/134 (38.1%) patients. On retrospective review of images and videoclips, ovarian stromal edema with or without peripherally displaced antral follicles (201/254; 79.1%) and the whirlpool sign (139/153; 90.8%) were the most commonly detected features of adnexal torsion.
CONCLUSION
Most patients with surgically confirmed adnexal torsion are of reproductive age and present with acute or subacute pain. Common ultrasound signs are an enlarged adnexa, the whirlpool sign, ovarian stromal edema with or without peripherally displaced antral follicles and free fluid in the pelvis. The follicular ring sign and absence of Doppler signals in the twisted organ are slightly less common signs. Recognizing ultrasound signs of adnexal torsion is important so that the correct treatment, i.e. surgery without delay, can be offered. Copyright © 2020 ISUOG. Published by John Wiley & Sons Ltd.

Indirect inguinal hernia is a common congenital abnormality in children. In female infants, herniation of the ovaries, fallopian tubes and uterus has been reported. Herniation of the ovaries is a rare congenital condition that may be complicated by strangulation, torsion, and infertility. A 6-week-old female infant presented with visible swelling in the right inguinal region. This case highlights the utility of ultrasonography as a cheap and easily available imaging technique that can be used for the characterization of the hernial contents, and guide the management, further accentuated by the use of color Doppler imaging, of this subtle but crucial entity.

Review
Adnexal masses during pregnancy are a relatively uncommon entity. Their clinical management is challenging given the overlapping features of certain entities on imaging and histopathology, which can mimic malignancy, and the potential side effects to the mother and fetus, whether expectant management versus surgery is pursued. Ultrasonography with Doppler evaluation is the modality of choice for evaluating adnexal masses during pregnancy. Magnetic resonance imaging is the second-line modality useful when US findings are inconclusive/indeterminate. Most adnexal masses in pregnant patients are benign in origin (e.g., functional cysts, mature cystic teratoma, decidualization of endometrioma), but a few are malignant in origin (e.g., dysgerminoma, granulosa cell tumor). Most cases of adnexal masses are asymptomatic, but complications such as ovarian torsion can occur. This review aims to familiarize the radiologist with the imaging of adnexal lesions during pregnancy so that the radiologist can identify ovarian cancer. Specifically, the review will detail the most common benign and malignant adnexal masses in pregnancy, mimickers, and their corresponding imaging findings on US and MRI.

BACKGROUND
A paraovarian cyst (POC) is located between the ovary and the fallopian tube. In many cases POCs are diagnosed and managed as ovarian cysts. But since POC are a distinct entity in their clinical presentation and surgical intervention, they should be better defined.
OBJECTIVES
To describe the clinical perioperative and operative characteristics of patients with POCs in order to improve pre-operative diagnosis and management.
METHODS
A retrospective cohort study of patients with an operative diagnosis of POC between 2007 and 2019 in a single university-affiliated tertiary care medical center was included. Demographic characteristics as well as symptoms, sonographic appearance, surgery findings, and histology results were retrieved from electronic medical records.
RESULTS
During the study period 114 patients were surgically diagnosed with POC, 57.9% were in their reproductive years and 24.6% were adolescents. Most presented with abdominal pain (77.2%). Preoperative sonographic exams accurately diagnosed POC in only 44.7% of cases, and 50.9% underwent surgery due to suspected torsion, which was surgically confirmed in 70.7% of cases. Among women with confirmed torsion, 28.9% involved the fallopian tube without involvement of the ipsilateral ovary. Histology results showed benign cysts in all cases, except two, with a pathological diagnosis of serous borderline tumor.
CONCLUSIONS
POC should always be part of the differential diagnosis of women presenting with lower abdominal pain and sonographic evidence of adnexal cysts. If POC is suspected there should be a high level of suspicion for adnexal torsion and low threshold for surgical intervention, especially in adolescent, population who are prone to torsion.

Ovarian torsion is defined as partial or complete rotation of the ovarian vascular pedicle and causes obstruction to venous outflow and arterial inflow. Teenage patient was referred to the gynecology ward with pain located in the lower, right abdomen, after an initial misdiagnosis of a dermoid cyst. The patient was diagnosed with a torsion of the right ovarian peduncle. The patient was given diastolic drugs and was discharged in good general condition two days later after the symptoms had resolved. Final USG showed normally vasculated corpus luteum. Among the various treatment options, the wait-and-watch attitude turned out to be the best solution. It is particularly important in the case of young patients, who are planning pregnancy in the future.
