RESUMO

The Appropriateness Criteria for the imaging screening of second and third trimester fetuses for anomalies are presented for fetuses that are low risk, high risk, have had soft markers detected on ultrasound, and have had major anomalies detected on ultrasound. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision include an extensive analysis of current medical literature from peer reviewed journals and the application of well-established methodologies (RAND/UCLA Appropriateness Method and Grading of Recommendations Assessment, Development, and Evaluation or GRADE) to rate the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where evidence is lacking or equivocal, expert opinion may supplement the available evidence to recommend imaging or treatment.

RESUMO

This article discusses the role of Computed tomography (CT) and MR imaging in gynecologic malignancies by reviewing epidemiology, histologic subtypes, and staging systems. Imaging findings specific to different gynecologic malignancies on CT and MR imaging are reviewed and the advantages of each imaging modality discussed. Imaging of endometrial, cervical, and ovarian cancer is reviewed in depth, with a brief discussion of rare gynecologic cancers.

RESUMO

Lymphatic malformations (LMs) are congenital lymphatic lesions that impose significant and costly morbidities on affected patients. Treatment options are limited due to incomplete understanding of LM pathobiology. Expression of an activated ß2-adrenergic receptor has been described in LM tissue, suggesting that this pathway may contribute to the clinical manifestations of LM. We hypothesized that propranolol, a ß-adrenergic receptor antagonist, might improve symptoms of patients with LMs and lymphatic anomalies. A retrospective chart review of patients treated with propranolol as an adjunct therapy was conducted; analyses included demographic characteristics, clinical features, and response to propranolol. Three patients with cystic and noncystic LMs displayed clinical improvement at a minimum dose of 0.7 mg/kg/d, whereas symptomatic relapses were observed when propranolol doses dropped below this threshold. Two patients with Klippel-Trenaunay syndrome demonstrated partial clinical responses with reduced edema. The fetus of a mother treated with propranolol from a gestational age of 35 weeks through delivery displayed arrested growth of a cervicofacial LM. Our retrospective review suggests that propranolol improved symptoms in a subset of patients with lymphatic anomalies. Propranolol treatment may also limit the growth of congenital LMs in utero.

RESUMO

Postpartum and posttermination complications are common causes of morbidity and mortality in women of reproductive age. These complications can be broadly categorized into vascular, infectious, surgical, and neoplastic etiologies, or are due to ectopic implantation of placental or endometrial tissue. Causes of postpartum vascular complications include retained products of conception, arteriovenous malformation, and pseudoaneurysm. Infectious entities include endometritis, abscess, wound cellulitis, and pelvic septic thrombophlebitis. Postsurgical complications include uterine scar dehiscence, bladder flap hematoma, and subfascial hematoma. Neoplastic complications include the spectrum of gestational trophoblastic neoplasms. Ectopic tissue implantation complications include abnormal placentation and uterine scar endometriosis. Imaging is essential for diagnosis, and radiologists must be familiar with and aware of these entities so that accurate treatment and management can be obtained. In this review, we illustrate the imaging findings of common postpartum and posttermination complications on ultrasound, computed tomography, and magnetic resonance imaging.

RESUMO

BACKGROUND: Currently a leading indication for cesarean hysterectomy among multiparous women, placenta accreta is associated with significant maternal morbidity and mortality. CASE: A 34-year-old woman with a pregnancy complicated by placenta previa and previous cesarean deliveries was transferred to our institution following late diagnosis of placenta percreta. She underwent cesarean hysterectomy complicated by substantial hemorrhage. Massive blood product replacement precipitated severe hyperkaIemia and hypocalcemia with resultant asystole. Cardiac bypass with concomitant obligate anticoagulation was temporarily required while normalizing the patient's electrolytes. Numerous surgical and medical interventions were required to achieve hemostasis, and the patient survived to hospital discharge with moderate residual morbidity. CONCLUSION: Optimal management of placenta accreta requires a multidisciplinary approach within a tertiary center possessing extensive resources necessary for managing the most severe complications.

RESUMO

Any significant deviation from a woman's established menstrual pattern may be considered abnormal uterine bleeding, and several factors direct evaluation of a patient with such bleeding. Premenopausal disorders that are well evaluated with ultrasound (US) include endometriosis, adenomyosis, and leiomyomas. A positive pregnancy test in a woman of childbearing age prompts a search for an intrauterine pregnancy. Possible complications that may contribute to bleeding include ectopic pregnancy; placental factors including position, trauma, and infection; gestational trophoblastic disease; preterm labor; and postpartum complications. Atrophic changes, hormonal status, and carcinoma are considerations in the postmenopausal patient with abnormal uterine bleeding. Foreign bodies, trauma, infection, polyps, and iatrogenic causes can be observed in all groups. Differential diagnoses for abnormal uterine bleeding in premenopausal, pregnant, and postmenopausal patients are well evaluated with US, and US techniques have greatly facilitated evaluation of pelvic disease. Urgent and emergent conditions such as ectopic pregnancy, placenta previa, and preterm labor are readily identifiable.
