Characterisation of computed tomography angiography findings in paediatric patients with heterotaxy.

Background: Heterotaxy refers to the abnormal arrangement of organs across the left-right axis and is typically associated with complex cardiovascular malformations.

Objective: To characterise the range of cardiac and extracardiac CT angiography findings in children with heterotaxy using the latest nomenclature consensus and to compare the different types of isomerism.

Materials And Methods: We retrospectively analysed the data of 64 consecutive paediatric patients referred to our tertiary paediatric cardiovascular centre who underwent CT angiography for the evaluation of known or suspected heterotaxy within a 52-month period.

Fetal segmental spinal dysgenesis and unusual segmental agenesis of the anterior spinal artery.

Segmental spinal dysgenesis (SSD) is a rare congenital spinal abnormality characterized by segmental dysgenesis or agenesis of the thoracolumbar or lumbar spine, congenital kyphosis, and abnormal configuration of the underlying spinal cord. A unique feature of SSD is that the vertebrae are present above and below the defect, and there is often a lower cord segment in the caudal spinal canal. We report a fetal MRI case of SSD with postmortem and neuropathological correlations.
