“…It was first described in 1941 by American psychiatrist Clemens E. Benda and represents a dilatation of the lateral or occipital horns of the lateral brain ventricles, and may be the cause of the congenital stroke (1, 2). On fetal MRI it is diagnosed as the diameter of the rear horns of lateral brain chambers exceeds 10 mm on axial scans (3). The most common pathology of the thoracic cavity in the fetus is CCAM (congenital cystic adenomatoid malformation).…”

Introduction: Fetal Magnetic Resonance Imaging (MRI) is an imaging method for displaying anatomical structures of the fetus without ionizing radiation and it has been in use since the MRI has been used for the analysis of the adult human body. Aim: The aim of our paper is the two-year retrospective analysis of fetal MRI examinations for the purpose of presenting various pathological conditions of the fetuses. Methods: A total of 59 fetal MRI examinations were performed on pregnant women in the time period 2016 to 2018 at the Radiology Clinic at Sarajevo University Clinical Center, on Siemens and Toshiba 1.5 Tesla scanners. All cases were referred by gynecologists who suspected a fetal pathology. The comparison of the fetal age at which the congenital anomalies are usually detected is performed using the univariate analysis of variance and the Student t test, at the 95% level of confidence. Results: Of the total of 59 fetal MRI examinations, 2 fetuses (3,4%) were healthy, while pathology of the head and CNS was found in 26 fetuses (44,2%), thoracic cavity pathology in 5 fetuses (8,5%), abdominal cavity pathology in 18 fetuses (30,6%), pathology of extremities in 2 fetuses (3,4%), spinal cord pathology in one fetus (1,7%), and in 3 fetuses associated anomalies were found (5,1%). The pathology of the uterus and placenta was found in two pregnant women (3,4%). Conclusion: Prenatal MRI provides extremely useful information in cases where the ultrasound examination of the fetus is insufficient due to the size and position of the fetus. MRI is a key tool in deciding whether to continue or stop the further development of the fetus.

Objectives: To evaluate the diagnostic value and clinical application of prenatal ultrasonography (US) and Magnetic Resonance Imaging (MRI) for different types of fetal Agenesis of the Corpus Callosum (ACC). Material and methods: There were 42 cases of fetal ACC discovered by routine US, including complete ACC 18 cases and partial ACC 24 cases, checked by MRI within 1 week. The results were confirmed by head ultrasound after birth or brain biopsy after labor induction. Results: From prenatal ultrasonic diagnosis, 18 cases were complete ACC and 24 cases were partial ACC. MRI was able to find complete ACC in 11 cases, partial ACC in 16 cases, and non-ACC in 15 cases. Labor induction or birth confirmed that, 11 cases were complete ACC, 14 cases were partial ACC, and 17 cases were non-ACC.The results of different types of ACC were detected by ultrasound and MRI were statistically significant (p < 0.05).MRI examination was superior to ultrasound in specificity, positive predictive value, negative predictive value, Youden index, and diagnostic index. Conclusions: MRI is high specific degrees, diagnostic performance is satisfactory, should be use as a necessary method for prenatal definitive diagnosis of ACC. However, prenatal ultrasound can be tested repeatedly and can be combined with blood flow imaging detection in real time, and it is still the preferred method for screening fetal structural malformation in a comprehensive way, which is suitable for general screening of ACC.

Spotlight on the pediatric eye: a pictorial review of orbital anatomy and congenital orbital pathologies

Orbital lesions in the pediatric population vary from adults in terms of their presentation, unique pathology, and imaging characteristics. The prompt and accurate diagnosis of these lesions is imperative to prevent serious consequences in terms of visual impairment and disfigurement. Along with dedicated ophthalmologic examination, imaging is instrumental in characterizing these lesions, both for accurate diagnosis and subsequent management. In our pictorial essay, we provide a basic review of orbital embryology, anatomy, and congenital orbital pathologies, with emphasis on radiological findings.
