The 3D printed models scored higher than conventional imaging, with respect to most aspects of the surface spatial orientation and intracardiac anatomy. The models are a useful adjunct in preoperative assessment of complex DORV. The unique scale helps quantify the advantages and limitations of the 3D heart models.

We report a rare case of ectopic pregnancy occurring in the scar of a previous caesarean section, diagnosed by ultrasonography and confirmed by 3.0-T magnetic resonance imaging of pelvis. We present the clinical details and imaging findings, followed by discussion of the etiology, pathogenesis, and imaging of this condition.

A three-dimensional (3D) printed heart model based on contrast-enhanced MR angiography data was obtained in an 8-month-old male child with double-outlet right ventricle. The model could successfully show the spatial relationship between the aortic annulus, the pulmonary valve and the ventricular septal defect. The patient underwent complete intracardiac repair based on the 3D model. MR angiography images could be successfully used to create a true-size 3D heart model, which significantly helped in assessing the routability of the ventricular septal defect to the aorta, leading to successful intracardiac repair in our patient.

Neural tube defects are common pediatric surgical conditions. Among them, encephalocele represents the protrusion of the brain component through the cranial defect. Double encephalocele is a rare entity, with only five cases reported in literature.We report a case of congenital double encephalocele with review of literature.
