Naujai atsiradę priepuoliai nėštumo metu yra reta, bet gana sudėtinga situacija. Priepuoliai nėštumo metu atsiranda dėl priežasčių, kurias galima priskirti trims kategorijoms: anksčiau diagnozuota arba naujai atsiradusi epilepsija, naujai atsiradę priepuoliai dėl su nėštumu nesusijusių būklių ir nėštumui specifiškos arba dažnai nėštumo metu pasitaikančios būklės, ypač eklampsija. Elektroencefalografija (EEG) ir neurovizualiniai tyrimai padeda diferencijuoti šias būkles. Tačiau nėščių pacienčių, patiriančių priepuolius, neurovizualiniai tyrimai ir gydymas kelia daug iššūkių, kadangi trūksta su nėščiomis moterimis atliktų klinikinių atsitiktinių imčių tyrimų. Straipsnyje pateikiame klinikinį atvejį, kai 31 metų 29-ą savaitę pirmą kartą nėščiai moteriai buvo diagnozuota naujai atsiradusi epilepsija, pasireiškusi abipusiais toniniais-kloniniais traukuliais ir EEG fiksuotu lėtu patologiniu aktyvumu, be neurologinio deficito ar anomalijų magnetinio rezonanso tyrime.

“…Evaluation of adnexal masses in the gravid population is challenging because they may undergo morphologic changes due to the altered hormonal status and may demonstrate features that can mimic malignancy on imaging. The most common pregnancy-related adnexal masses are the corpus luteum of pregnancy and the theca lutein cyst; both are expected to resolve after gestational week 18, although a few may persist until after delivery [ 34 ]. Other conditions that can mimic malignancy at imaging are decidualized endometriomas and leiomyomas with red degeneration.…”

Imaging plays a pivotal role in the diagnostic approach of women with suspected ovarian cancer. MRI is widely used for preoperative characterization and risk stratification of adnexal masses. While epithelial ovarian cancer (EOC) has typical findings on MRI; there are several benign and malignant pelvic conditions that may mimic its appearance on imaging. Knowledge of the origin and imaging characteristics of a pelvic mass will help radiologists diagnose ovarian cancer promptly and accurately. Finally, in special subgroups, including adolescents and gravid population, the prevalence of various ovarian tumors differs from that of the general population and there are conditions which uniquely manifest during these periods of life.

Pregnancy is a delicate state, during which timely investigation of possible physiological anomalies is essential to reduce the risk of maternal and fetal complications. Medical imaging encompasses different technologies to image the human body for the diagnosis, course of treatment management, and follow-up of diseases. Ultrasound (US) is currently the imaging system of choice for pregnant patients. However, sonographic evaluations can be non-effective or give ambiguous results. Therefore, magnetic resonance imaging (MRI), due to its excellent tissue penetration, the possibility of acquisition of three-dimensional anatomical information, and its high spatial resolution, is considered a valid diagnostical alternative. Nevertheless, currently employed contrast agents to improve the MRI image quality are harmful to the fetus. Because of their ability to cross the placenta, their use on pregnant patients is avoided. This review will firstly recapitulate the most common non-obstetrical, obstetrical, and fetal indications for magnetic resonance imaging on pregnant women. Fetal safety risks, due to the use of strong magnetic fields and exogenous contrast agents, will be presented. Then, possible advantages of nanostructured contrast agents compared to current molecular ones are explored. Nanosystems’ characteristics affecting contrast efficiency, and their potential for improving contrast-enhanced MRI’s safety in pregnant women, are discussed. Lastly, promising examples of nanoparticles as safer alternatives to current MRI contrast agents in pregnancy are discussed.
