: Identifying the etiology of acute pelvic pain in girls is often clinically challenging. Particularly in young girls, it is often difficult to determine if acute pelvic symptoms are originating from a gynecologic source or from a genitourinary or gastrointestinal etiology based on the child's clinical examination alone. Therefore, imaging plays a key role in establishing a diagnosis and in directing medical and surgical treatment. Pediatric gynecologic conditions, which can present acutely with pain or mass or both include ovarian torsion, hematometrocolpos, pelvic inflammatory disease, inguinal hernias containing an ovary or the uterus or both, adnexal cysts, pregnancy, vaginal foreign bodies, and ovarian vein thrombosis...

: A 27-year-old primiparous woman with 28 weeks gestational age was admitted to our hospital with worsening shortness of breath. She was diagnosed with Ebstein's anomaly three years ago, but preferred to be left untreated. The patient was not cyanotic and her vital signs were stable. Her ECG showed incomplete RBBB and prolonged PR-interval. Blood tests revealed mild anemia. Observation of two-dimensional echo with color flow Doppler study showed Ebstein's anomaly with PFO as additional defects, EF of 57%, LV and LA dilatation, RV atrialization, severe TR, and moderate PH with RVSP of 44...

BACKGROUND: Fetal echocardiography (FECG) is a key screening tool for prenatal cardiac abnormalities. Herein, we examined the ultrasonic factors determining prenatal ultrasonic diagnosis of isolated ventricular septal defect (IVSD). METHODS: The diagnostic role of ultrasonic factors was investigated in patients in middle or late pregnancy, diagnosed with IVSD by FECG and confirmed using postnatal echocardiography. RESULTS: One hundred and six patients with IVSD were enrolled; the majority had perimembranous VSD...

INTRODUCTION: Azoospermia causes about 10% of male infertility and the best therapeutic option is the retrieval of sperm from testis or epididymis. MATERIAL AND METHODS: From Juanary 2008 to June 2016, 92 men (median 36 years; range: 25-54 years) were submitted in 47 cases to TESE (testicular sperm extraction) and in 45 cases to PESA (percutaneous epididymal sperm aspiration) for secretory and obstructive azoospermia, respectively; moreover, all the patients previously underwent color Doppler ultrasound of the testis and transrectal ultrasound of the prostate...

Paraovarian cysts are a rare pathology, constituting 10-20% of the adnexal masses. The origin can be represented by paramesonephric ducts (Hydatid cysts of Morgagni), vestiges of mesonephric ducts also represented by mesothelium, or neoplastic (cystadenomas or cystadenofibromas) that are mostly benign. Borderline or malignant paraovarian tumors are encountered less often. This article presents a case of paraovarian cyst in a 37-year-old patient, with a history of 2 pregnancies, completed by cesarean. The patient sought medical attention for an asymptomatic voluminous ovarian cyst, detected in a routine ultrasound scan...

Caesarean scar pregnancy is one of the rarest forms of ectopic pregnancy. Transvaginal ultrasound and color flow Doppler provides a high diagnostic accuracy. A delay in diagnosis and treatment can lead to uterine rupture, major hemorrhage, hysterectomy and serious maternal morbidity and mortality. Early diagnosis can offer treatment options of avoiding uterine rupture and hemorrhage, thus preserving the uterus and future fertility. Primary health care provider should know about this rare entity, because if diagnosed timely, and referral to specialized centre is done without delay will definitely save maternal morbidity and mortality...

REVIEW

The evaluation of amniotic fluid volume (AFV) is an established part of the antenatal surveillance of pregnancies at risk for an adverse pregnancy outcome. The two most commonly used ultrasound techniques to estimate AFV are the amniotic fluid index (AFI) and the single deepest pocket (SDP). Four studies have defined normal AFVs, and although their normal volumes have similarities, there are also differences primarily due to the statistical methodology used in each study. Dye-determined AFV correlates with ultrasound estimates for normal fluid volumes but correlates poorly for oligohydramnios and polyhydramnios...

OBJECTIVE: To assess the natural history and outcome of fetal pulmonary stenosis (PS), particularly that detected at 14-17 weeks' gestation. METHODS: In this retrospective study we searched an electronic database of women from the general Israeli population attending a private ultrasound institute (Al-Kol ultrasound institute in Haifa) for routine complete early fetal ultrasound, including all fetal systems and a fetal echocardiogram, between 2004 and 2015. Ninety-seven percent of the women were at low risk of fetal malformations, and 3% had risk factors such as maternal Type-1 diabetes mellitus, exposure during pregnancy to teratogenic drugs, or anomalies in previous pregnancies or in other family members...

PURPOSE OF REVIEW: Placental implantation abnormalities (PIAs) comprise a large group of disorders associated with significant maternal, fetal, and neonatal morbidity. RECENT FINDINGS: Risk factors include prior uterine surgery/myometrial scarring and the presence of placenta previa with or without prior cesarean delivery. Newly identified risk factors include previous prelabor cesarean delivery and previous postpartum hemorrhage. PIAs contribute substantially to preterm birth with prematurity rates ranging from 38 to 82%...

We report 2 cases of true uterine artery aneurysms diagnosed during pregnancy. Both cases presented with nonspecific symptoms such as urethral obstruction, minimal vaginal bleeding and lower abdominal pain in the 2nd trimester. Both aneurysms were diagnosed by color Doppler ultrasound. In the first case labor was induced at 37 + 4 weeks of gestation. However, due to sudden fetal distress and maternal abdominal pain, an emergency Caesarean section was performed during labor, and 3 liters of intra-peritoneal blood were encountered upon laparotomy, secondary to a ruptured uterine artery aneurysm...

A case of congenital renal arteriovenous fistula (AVF) complicating pregnancy with gross hematuria was managed successfully by superselective embolization with metallic coils. The patient was in the first trimester of her pregnancy at 12 weeks of gestation. The AVF was detected by color Doppler sonography and confirmed by renal arteriography. Because of its easy accessibility and absence of irradiation, ultrasound is the first choice for pregnant patients. Color Doppler ultrasound is effective in diagnosing AVF, and it is also helpful in the long-term followup after treatment...

OBJECTIVE: Vein of Galen aneurysmal malformation (VGAM) is a rare anomaly in which an adequate perinatal management may warrant good neurological outcome. However, most fetal series are too scant to allow reliable statistical assessment of poor prognostic factors. Aim of this paper is to assess, in a two-center series of 49 cases, the prognostic value of several prenatal variables. The primary endpoint of the analysis is to identify possible prenatal indicators of poor outcome, in terms of mortality and cerebral disabilities...

We present our experience of using new 3-dimensional color/power Doppler sonography (HDliveFlow; GE Healthcare Japan, Tokyo, Japan) with the HD live silhouette mode for diagnosing complete molar pregnancy in the first trimester and differentiating it from missed abortion with hydropic degeneration. In the case of a complete mole, color Doppler sonography showed numerous vesicles without blood vessels, whereas HDliveFlow with the HD live silhouette mode clearly depicted these vesicles forming a mass with the clear demarcation of its edges and showed no blood flow inside the mass...
