A case of bronchopulmonary sequestration combined with congenital pulmonary airway malformation prenatally diagnosed as having two aberrant arteries originating from the celiac artery.

We report a case of BPS combined with CPAM prenatally diagnosed as having two aberrant arteries from the celiac artery by fetal 3D-US. Although the pattern of arterial feeding vessels was extremely rare in our case, the vasculature images obtained using fetal 3D-US were comparable to those obtained using postnatal CT angiography.

Spontaneous Complete Chorioamniotic Membrane Separation in a Fetus With Ileal Atresia and Umbilical Cord Ulcer: A Case Report.

Spontaneous complete chorioamniotic membrane separation (cCMS) is rare and associated with adverse perinatal outcomes, such as intrauterine fetal death. Herein, we present a case of spontaneous cCMS in a fetus with ileal atresia and umbilical cord ulcers. In our case, we detected spontaneous cCMS on ultrasonography at 35 weeks of gestation. On the same day, a female infant weighing 2134 g was delivered via cesarean section. Pathological examination of the placenta confirmed cCMS and umbilical cord ulcers. When cCMS is evident in late preterm infants, the fetus should be carefully monitored and considered for delivery.

Prenatal features of congenital peribronchial myofibroblastic tumor.

Here, we report a case of a congenital peribronchial myofibroblastic tumor (CPMT). A 34-year-old primigravida was referred to our hospital at 31 gestation weeks because of suspected congenital pulmonary airway malformation (CPAM). Fetal ultrasonography showed a mass measuring 4.6 × 4.0 × 3.9 cm with mixed high and low echogenicity in the left lung, which was associated with microvascular blood flow in the tumor. Fetal magnetic resonance imaging (MRI) revealed a low-intensity left lobe lung lesion on a T2-weighted image. These findings suggested that the mass was a CPAM with atypical hypointense findings on MRI T2-weighted images or a rare primary pulmonary tumor, such as a CPMT. Unfortunately, the fetus died in utero at 34 gestation weeks due to cardiovascular failure, which could have resulted from direct encasement of the great vessels or cardiac compression due to rapid tumor growth. The autopsy findings confirmed the diagnosis of CPMT. Primary pulmonary tumors, such as CPMT, are extremely rare lung diseases that develop in utero. These tumors often rapidly grow during pregnancy, resulting in intrauterine fetal death. However, if the patient survives surgical mass resection, the prognosis is good. Given the adverse outcomes observed in our case, careful fetal monitoring is required in case of suspected CPMT during the third trimester of pregnancy. Moreover, in case the well-being of the fetus cannot be assured, immediate delivery should be considered, even in the preterm period, followed by surgery.

Prenatal aortic arch development in double aortic arch: Understanding postnatal closure of left aortic arch: A case report.

Double aortic arch (DAA) is a rare congenital abnormality characterized by a vascular ring that often requires surgical intervention due to respiratory complications. The DAA and right aortic arch with mirror-image branches (RAA-MB) represent abnormalities in development of the aortic arch. However, prognosis differs significantly, as the DAA forms vascular rings, whereas the RAA-MB typically does not. Distinguishing between the conditions becomes particularly challenging in cases of DAA with closure of the posterior portion of the left aortic arch (LAA) because the postnatal manifestations closely resemble those of RAA-MB. Herein, we present a case of DAA in which longitudinal observation of the LAA and RAA diameters during pregnancy aimed in predicting postnatal closure of the LAA. A 37-year-old female with suspected DAA was referred to our hospital at 26 weeks of gestation. Initial measurements revealed comparable diameters for the LAA and RAA; however, the LAA diameter decreased to approximately half that of the RAA by term owing to growth restrictions. Postnatal contrast computed tomography confirmed the closure of the posterior portion of the LAA and RAA with Kommerell diverticulum. Our findings suggest that careful monitoring of DAA throughout fetal development, especially during the third trimester, may aid in predicting atretic changes in the nondominant arch after birth, allowing an easy distinction between the DAA and RAA-MB after birth.
