    Abstract Choriocarcinoma of the ovary is a rare, highly malignant tumor showing malignant trophoblastic cells and produces human chorionic gonadotropins. It can be classified as gestational and non-gestational choriocarcinoma. Non-gestational choriocarcinoma is extremely rare. Treatment is Methotrexate-based chemotherapy for the gestational type. This case study is a rare case of ovarian choriocarcinoma managed by surgical resection, followed by methotrexate-based chemotherapy, and aimed to evaluate the ultrasound characteristics of ovarian choriocarcinoma and how to arrive at the diagnosis. In cases with an elevated serum beta-human chorionic gonadotropin (beta hCG), the finding of a highly vascularized adnexal mass on ultrasound evaluation should be underlined as a clue for suspecting choriocarcinoma, particularly if the female was young with no marriage history or history of sexual intercourse and also to be highly considered in married females with history of repeated abortions, molar pregnancy or uterine choriocarcinoma.

    Abstract Aim: Abnormal uterine vascular pattern can be observed during transvaginal ultrasound examination used for investigating post-abortion bleeding and secondary postpartum hemorrhage. The purpose of this series of cases was to evaluate almost all the rare causes of uterine vascular abnormalities linked to pregnancy complications, and determine how to arrive at the diagnosis to optimize patient management, which is crucial for preventing life-threatening massive vaginal bleeding.
    Material and methods: Retrospective observational case series study including 20 women with postpartum or post-abortion vaginal bleeding who were found to have an abnormal uterine vascular pattern during a transvaginal color duplex assessment.
    Results: The study yielded the following findings: 10 cases of enhanced myometrial vascularity, two cases of pseudoaneurysm in the uterine artery, one case of myometrial venous varix, one case of large uterine venous pseudoaneurysm, one case of uterine arteriovenous malformation, one case of retained placental polyp, one case of invasive vesicular mole, and three cases of subinvolution of the placental implantation site.
    Conclusions: Transvaginal color duplex ultrasound plays a crucial role in detecting uterine vascular abnormalities as a cause of post-abortion or secondary postpartum hemorrhage and can help differentiate the pathologies responsible for the abnormal vascular pattern, which is highly recommended to optimize patient management.

    Abstract The current case report evaluated a female patient with a history of right salpingectomy subsequent to right tubal ectopic pregnancy that was presented with amenorrhea followed by vaginal bleeding and lower abdominal severe pain. The transvaginal ultrasound examination revealed the presence of ipsilateral right interstitial ectopic pregnancy. The patient was subjected to cornual wedge resection and uterine repair. The pathology report of the excised specimen revealed decidua, chorionic villi, and blood. Recurrent interstitial ectopic pregnancy after previous ipsilateral tubal ectopic pregnancy managed with salpingectomy is very rare, with only a few cases described in the literature. The current study was to evaluate and explain the occurrence of recurrent ectopic pregnancy after ipsilateral salpingectomy using the ultrasound.

    Abstract Background The intersphincteric plane (ISP) is a potential space between the external and the internal anal sphincters. About 90% of the perianal sepsis is caused by an obstruction of the ducts of anal glands with subsequent secondary bacterial infection. The imaging modalities used to diagnose perianal sepsis are the ultrasound via endoanal and transperineal routes and magnetic resonance imaging. Objective The study aimed to identify the various patterns of the ISP sepsis and their incidence among our study group and to clarify the significance of ISP in the pathogenesis of anorectal abscesses and various types of perianal fistula tracts, to optimize the surgical management. Methods Retrospective descriptive study in which 57 patients with an ISP sepsis were evaluated with full medical history, clinical exam, and ultrasound; the final diagnosis was based on combining the results of ultrasound, digital rectal examination under anesthesia, and the operative results. Results The current study showed many patterns of the ISP sepsis and estimated the incidence of each pattern among our study group; such patterns could be fistula tracts, sinus tracts, abscesses, intersphincteric abscess with supralevator extension, sinus with abscess formation, fistula with abscess formation, distension of the ISP with free pus, and other complex patterns like horse abscess, abscess with transsphincteric sinus, and ISP fistula/sinus with transsphincteric branches. Conclusion Understanding the role of the ISP in the pathogenesis of anorectal abscesses and perianal fistula tracts can help in reaching the optimum way of management.

    Abstract Background: The presence of ectopic functional endometrial glands and struma anywhere except in the lining of the uterine cavity is considered as endometriosis. Extrapelvic endometriosis involving the abdominal wall cesarean section scar is uncommonly seen, and it rarely involves the perineum, umbilicus, pleura, kidneys, lungs and liver. Objectives: The purpose of the present study is to highlight rare ectopic sites, explain the pathogenesis of extrapelvic endometriosis, and evaluate the diagnostic significance of clinical findings, serum CA 125 level, and ultrasonography. Materials and methods: 24 female patients with extrapelvic endometriomas in whom the final diagnosis was based on the surgical results and histopathological reports of the excised specimens. The patients underwent a clinical examination, an ultrasound scan, and evaluation of the serum CA 125 level. They were also examined by transvaginal ultrasound to rule out ovarian endometriosis or uterine adenomyosis. They were further subjected to abdominal wall ultrasound in cases of cesarean section scar or umbilical region swellings, and transperineal ultrasound for perianal lesions. Transvaginal ultrasound was performed in patients with perineal endometrioma to assess the relation between the lesion and the external anal sphincter. Results: In 19 patients, abdominal wall cesarean section scar endometrioma was detected. Three patients had perianal endometriomas, and two patients – umbilical endometriomas. Conclusion: Ultrasound scanning was a useful diagnostic tool to evaluate extrapelvic endometriosis and its extension, especially in cases without typical clinical features that can be suggestive of endometrioma, low diagnostic sensitivity of serum CA 125, and low incidence of concomitant intrapelvic disease.

    Abstract The current study evaluated two cases of pervaginal bleeding subsequent of intrauterine arterial pseudoaneurysm. Each case was complaining of intermittent attacks of heavy vaginal bleeding: one case with history of cesarean section and the other case after uterine curettage. Intrauterine arterial pseudoaneurysm can be caused by a traumatic injury to the vessel wall with subsequent formation of periarterial hematoma that liquefies forming periarterial bloody cyst, which communicates through the narrow neck with the arterial lumen. Transvaginal ultrasound aided with color duplex capability is an accurate tool for assessment.

    Abstract The pandemic of COVID-19 had started in Wuhan city china in late 2019 with a subsequent worldwide spread. The viral infection can seriousely affect multiple organs mainly lungs, kidneys, heart, liver and brain and may lead to respiratory, renal, cardiac or hepatic failure.Vascular thrombosis of unexplained mechanism that may lead to widespread blood clots in multiple organs and cytokine storms that result of overstimulation of the immune system subsequent of lung damage may lead to sudden decompensation due to hypotension and more damage to liver, kidney, brain or lungs.Until now no drug had proved efficient in getting rid of the problem and controlling the pandemic mainly depends on preventive measures.Many preventive measures can be considered to prevent the worldwide spread of viral transmission. Polyunsaturated long chain fatty acids (PUFAs) and the medium chain saturated fatty acids (MCSFAs) and their corresponding monoglycerides had high antiviral activities against the enveloped viruses which reach to more than 10,000 -fold reduction in the viral titres in vitro and in vivo after testing of its gastric aspirate, and can contribute to the systemic immunity against the enveloped viruses.

    Abstract Introduction: Many uncommon obstetric and gynecologic problems associated with pregnancy and the early postpartum period can lead to severe abdominal pain and be life-threatening. The patient will be in urgent need of a quick and accurate decision. The means of management will depend on the ability to differentiate between these problems to achieve an optimal diagnosis.
    Materials and methods: 30 pregnant females attended a private obstetric ultrasound clinic with clinical picture of acute abdomen with pregnancy. All were subjected to an ultrasound exam, the results were recorded, and the final diagnosis was reached based on the postoperative results.
    Results: Patients were classified according to their duration of pregnancy into cases with acute abdomen that occurred during the first trimester, during the second trimester, during the third trimester, and in the early postpartum period.
    Conclusion: Ultrasonography is a valuable tool for detecting the etiology and guiding the management in cases of emergency situations faced by the obstetrician and gynecologist during pregnancy and the early postpartum period.
